√ is the code to add sq.root symbol. Thank you:)

Examples to Find Square Root in JavaScript, For example, the square root of 9 is 3 because 3 X 3 is 9. Similarly, the square root of 25 is 5 since 5 x5 is 25. Now let’s convert the above mathematical equation into a Javascript code. Javascript uses the Math object for a variety of mathematical operations. This has many properties and functions to perform a variety of …

Correct square root symbol won’t present

we use Telerik Editor, and now some of our users can’t see the Square Root symbol on chrome browser , and others with chrome (same version) can see without any problem. In IE it works perfect for all users, for those that can’t see, this symbol is shown instead:

there is some more codes to present square root correct in all browsers such as:

but for now, replacing the representation of this char in the editor and in the whole already exist items in the DB will be too complicated, any idea why some of the users can’t see it in chrome with the current representation?

p.s. this problem related to more and many other symbols, they all belongs to the Symbol font-family

The problem is that your users have used the Symbol font, mistakenly thinking that they have entered the square root sign “√” when they have actually entered the letter O with diaeresis, “Ö”. An similar things have apparently happened for other characters, too. This is an old trick that has never worked properly, though often enough to create an illusion of working.

In the early days, the trick was used e.g. with Ö , and newer modifications like the use of CSS instead of font markup do not change the basics: you are giving a browser the letter “Ö” and telling it to render it using a font that does not contain it. Some browsers display whatever the Symbol font contains in place of “Ö”, but Firefox knows what the Symbol font is.

The solution is to use the correct characters and make your best effort at ensuring that your font-family list contains fonts that contain them.

As regards to existing data that plays with the trick, it needs to be converted. You need to analyze where you have such data and replace all non-Ascii characters (that appear as raw data , not as entities/references) by the characters they are meant to denote, as per the Symbol font. Be careful to not convert, say, the letter “Ö” when it is really meant to be “Ö”. For the conversion, see e.g. Symbol font – Unicode alternatives for Greek and special characters in HTML and SIL Mapping Files.

Is it possible to display numbers inside a square root, For a native solution. You could use combining character code &#x305 of UTF-8. It will combine the overline with previous codeblock. But be really careful with your font settings.

sqrt()

The sqrt() CSS function is an exponential function that returns the square root of a number.

The function pow(x, 0.5) is equivalent to sqrt(x) .

Syntax

/* A value */ width: calc(100px * sqrt(9)); /* 300px */ width: calc(100px * sqrt(25)); /* 500px */ width: calc(100px * sqrt(100)); /* 1000px */ 

Parameters

The sqrt(x) function accepts only one value as its parameter.

A calculation which resolves to a greater than or equal to 0.

Return value

• if x is +∞ , the result is +∞ .
• If x is 0⁻ , the result is 0⁻ .
• If x is less than 0 , the result is NaN .

Formal syntax

=
sqrt( )

=
[ [ ‘+’ | ‘-‘ ] ]*

=
[ [ ‘*’ | ‘/’ ] ]*

Examples

Scale sizes based on square root

This example shows how you can use the sqrt() function to calculate sizes.

HTML

div class="boxes"> div class="box">50pxdiv> div class="box one">100pxdiv> div class="box two">150pxdiv> div class="box three">200pxdiv> div> 

CSS

Here we are using CSS custom properties to define the sizes to be used. First, we declare the first size ( —size-0 ), which is then used to calculate the other sizes.

• —size-1 is calculated by multiplying the value of —size-0 (50px) by the square root of 4 (2), which results in 100px.
• —size-2 is calculated by multiplying the value of —size-0 (50px) by the square root of 9 (3), which results in 150px.
• —size-3 is calculated by multiplying the value of —size-0 (50px) by the square root of 16 (4), which results in 200px.

:root  --size-0: 50px; --size-1: calc(var(--size-0) * sqrt(4)); /* 100px */ --size-2: calc(var(--size-0) * sqrt(9)); /* 150px */ --size-3: calc(var(--size-0) * sqrt(16)); /* 200px */ > 

.boxes  display: flex; flex-wrap: wrap; justify-content: space-around; > .box  width: var(--size-0); height: var(--size-0); background-color: tomato; color: white; display: flex; align-items: center; justify-content: center; > 

The sizes are then applied as the width and height values of the selectors.

.one  width: var(--size-1); height: var(--size-1); > .two  width: var(--size-2); height: var(--size-2); > .three  width: var(--size-3); height: var(--size-3); >

How to code Square Root symbol in HTML, CSS and MathJax

Coding mathematical formulas in HTML is somewhat frustrating because HTML does not support formulas easily. It is possible to code simple mathematical equations with HTML markup without having to resort to using graphical images. The advantage of HTML and CSS over graphical images is that the display can be enlarged using the browser zoom or text-size options. When the Internet browser has JavaScript enabled, it is possible to use MathJax, a display engine for mathematics that works in all modern browsers.

A quadratic equation may be coded using the tag.

HTML provides the square root character entity √ (√) which is a single character. In order to code the square root symbol, the characters that follow the square root character must have an overline. This is accomplished by creating a span of characters with a CSS style «text-decoration:overline;» as in the following example:

Notice that the CSS style includes the nowrap option to keep the browser from splitting up the formula, and the formula within the square root has a leading and trailing non-blank space   to extend the overline one character beyond the formula.

If you try to apply the above technique to a formula such as X 2 + 1, the results don’t look quite right because the overline applied to the superscript may be higher for some browsers, or it may cross over the superscripted characters:

Square Roots with superscripts may be coded using a table with two rows and two columns. The upper row contains   to go over the square root symbol and enough underline characters to go over the formula. To avoid problems with rendering on different browsers, the table should use a widely availabe font family such as Verdana or Arial.

A technique that produces good results is to use a tag, instead of the tag, to control the size and position of the superscripts so that they will not go into the overline. For example:

The table technique may be expanded with additional rows to create quite complex expressions. The quadratic formula can be coded with a row where the overline in the denominator separates the numerator and denominator of the formula.

MathJax

MathJax is an open source JavaScript display engine for mathematics that works in all modern browsers. MathJax uses CSS and web fonts that make it possible to scale equations with surrounding text at all zoom levels. The documentation for MathJax is available at www.mathjax.org.

MathJax may be used in any web page by including the following JavaScript statement in the section of the web page.

The Mathematical Markup Language (MML) defined by the W3C organization can be found here: www.w3.org/TR/MathML3/. The markup uses labels in XML format for operators, identifiers, numbers, etc. and defines their relationships. The markup document has an appendix that lists the codes for the mathematical operators at: www.w3.org/TR/MathML3/appendixc.html. In the example below, the code − is used for the minus sign (−), ± is used for the plus or minus sign (±), is used to define a fraction consisting of two rows for the numerator and denominator, and defines the contents within the square root radical.

Although the markup is complicated, the use of MathJax facilitates the display of mathematical equations without having to use graphic images.

MathJax supports TeX, a typesetting system designed by Donald Knuth and released in 1978. A derivative product, LaTeX, was introduced in the early 1980s. Both TeX and LaTeX simplify the coding of formulas significantly. For example, the quadratic formula is coded within double dollar signs as follows:

to generate the following:

Documentation for LaTeX can be found at latex-project.org.
