In JavaScript Math object is used to perform mathematical tasks on numbers from (0-9). In this tutorial you will learn about Math Object.

There is a list of JavaScript Math methods with description.

Methods Description
abs() This mathed is used to returns the absolute value of the given number in JavaScript.
acos() This mathed is used to returns the arccosine of the given number in radians in JavaScript.
asin() This mathed is used to returns the arcsine of the given number in radians in JavaScript.
atan() This mathed is used to returns the arc-tangent of the given number in radians in JavaScript.
cbrt() This mathed is used to returns the cube root of the given number in JavaScript.
ceil() This mathed is used to returns a smallest integer value, greater than or equal to the given number in JavaScript.
cos() This mathed is used to returns the cosine of the given number in JavaScript.
cosh() This mathed is used to returns the hyperbolic cosine of the given number in JavaScript.
exp() This mathed is used to returns the exponential form of the given number in JavaScript.
floor() This mathed is used to returns largest integer value, lower than or equal to the given number in JavaScript.
hypot() This mathed is used to returns square root of sum of the squares of given numbers in JavaScript.
log() This mathed is used to returns natural logarithm of a number in JavaScript.
max() This mathed is used to returns maximum value of the given numbers in JavaScript.
min() This mathed is used to returns minimum value of the given numbers in JavaScript.
pow() This mathed is used to returns value of base to the power of exponent in JavaScript.
random() This mathed is used to returns random number between 0 (inclusive) and 1 (exclusive) in JavaScript.
round() This mathed is used to returns closest integer value of the given number in JavaScript.
sign() This mathed is used to returns the sign of the given number in JavaScript.
sin() This mathed is used to returns the sine of the given number in JavaScript.
sinh() This mathed is used to returns the hyperbolic sine of the given number in JavaScript.
sqrt() This mathed is used to returns the square root of the given number in JavaScript.
tan() This mathed is used to returns the tangent of the given number in JavaScript.
tanh() This mathed is used to returns the hyperbolic tangent of the given number in JavaScript.
trunc() This mathed is used to returns an integer part of the given number in JavaScript.

Example of Math.sqrt(n)

In this example math.sqrt(n) method to display the square root of the given number.

<script type = "text/javascript">
var a = Math.sqrt(16);
document.write("Value is: " + a); 
</script>                  
        

Output of above code


Example of Math.random()

In this example math.random() method to display the random number between 0 to 1.

<script type = "text/javascript">
document.write("Random value is: " + Math.random());
</script>                  
        

Output of above code


Example of Math.pow(m,n)

In this example math.pow(m,n) method to display the m to the power of n that is mn.

<script type = "text/javascript">
document.write("4 to the power of 5 is: " + Math.pow(4,5));
</script>                  
        

Output of above code


Example of Math.ceil(n)

In this example math.ceil(n) method to display the largest integer for the given number. For example 4 for 3.7, 6 for 5.9 etc.

<script type = "text/javascript">
document.write("Ceil of 2.6 is: " + Math.ceil(2.6));
</script>                  
        

Output of above code


Example of Math.abs(n)

In this example math.abs(n) method to display the absolute value for the given number. For example 4 for -4, 6.6 for -6.6 etc.

<script type = "text/javascript">
document.write("Absolute value of -5 is: " + Math.abs(-5));
</script>                  
        

Output of above code
