Last Updated :

Less.js is a simple CSS pre-processor that facilitates the creation of manageable, customizable, and reusable style sheets for websites. Because CSS is a dynamic style sheet language, it was chosen. Because LESS is adaptable, it works with a wide range of browsers. Only CSS that has been written in and processed using the CSS pre-processor, a programming language, can be used by web browsers. In addition to providing capabilities like variables, functions, mixins, and operations to help create dynamic CSS while maintaining backward compatibility, it is a CSS language extension.
In this article, we are going to discuss the Math acos() function, which is used to do the arc cosine function on a given value. Basically, it is used to find the inverse cos value of a value. This function takes a floating number or deg value or rad value as a parameter and performs an operation on that value and returns a number
Syntax:
acos(value)
Parameters:
- value: This is the only compulsory parameter for this function. This parameter takes a floating number.
Return type: This method returns a floating number.
Example 1: The code below demonstrates the usage and implementation of the Misc acos() function.
HTML
<!DOCTYPE html>
< html >
< head >
< link rel = "stylesheet" type = "text/css"
href = "style.css" />
</ head >
< body >
< h1 style = "color:green" >GeeksforGeeks</ h1 >
< h3 >< b >Less.js Math acos() Function</ b ></ h3 >
< div class = "c1" >
< p class = "p1" >
< strong >
acos(0.695)
< br > 0.80237643rad
</ strong >
</ p >
</ div >
</ body >
</ html >

styles.less:
CSS
@body-bg- color : #eeeeee ;
@dark: hsl( 25 , 71% , 8% );
@light: rgb ( 253 , 255 , 146 );
@val: acos( 0.695 );
body {
background-color : @body-bg-color;
}
.c 1 {
width : 500px * @val;
height : 250px * @val;
margin : 1 rem;
background-color : @dark;
}
.p 1 {
padding : 80px 0px 0px 120px ;
color : @light;
}
|
Now, to compile the above LESS code to CSS code, run the following command:
lessc style.less style.css
style.css: The CSS output of the above Less file was compiled.
CSS
body {
background-color : #eeeeee ;
}
.c 1 {
width : 401.188213px ;
height : 200.5941065px ;
margin : 0.80237643 rem;
background-color : hsl( 25 , 71% , 8% );
}
.p 1 {
padding : 80px 0px 0px 120px ;
color : #fdff92 ;
}

Output:
Example 2: The code below demonstrates the usage and implementation of the Misc acos() function along with isnumber type function if() and boolean logical functions.
