JavaScript Math Object
The Javascript Math object is used to perform mathematical operations on numbers.
Example 1: This example uses math object properties to return their values.
html
<h1>zambiatek</h1><h2>JavaScript Math Object</h2><p id="GFG"></p><!-- Script to return math property values --><script> document.getElementById("GFG").innerHTML = "Math.LN10: " + Math.LN10 + "<br>" + "Math.LOG2E: " + Math.LOG2E + "<br>" + "Math.Log10E: " + Math.LOG10E + "<br>" + "Math.SQRT2: " + Math.SQRT2 + "<br>" + "Math.SQRT1_2: " + Math.SQRT1_2 + "<br>" + "Math.LN2: " + Math.LN2 + "<br>" + "Math.E: " + Math.E + "<br>" + "Math.PI: " + Math.PI;</script> |
Output:
Example 2: Math object methods are used in this example.
html
<h1>GeeksForGeeks</h1><h2>JavaScript Math Object</h2><p id="GFG" style="color:green;"></p><!-- Script to use math object method --><script> document.getElementById("GFG").innerHTML = "<p><b>Math.abs(-4.7):</b> " + Math.abs(-4.7) + "</p>" + "<p><b>Math.ceil(4.4):</b> " + Math.ceil(4.4) + "</p>" + "<p><b>Math.floor(4.7):</b> " + Math.floor(4.7) + "</p>" + "<p><b>Math.sin(90 * Math.PI / 180):</b> " + Math.sin(90 * Math.PI / 180) + "</p>" + "<p><b>Math.min(0, 150, 30, 20, -8, -200):</b> " + Math.min(0, 150, 30, 20, -8, -200) + "</p>" + "<p><b>Math.random():</b> " + Math.random() + "</p>";</script> |
Output:
There are many math object properties which are listed below:
| Property | Description |
|---|---|
| Math.E | Euler’s number |
| Math.PI | PI |
| Math.SQRT2 | The square root of 2 |
| Math.SQRT1_2 | The square root of 1/2 |
| Math.LN2 | The natural logarithm of 2 |
| Math.LN10 | The natural logarithm of 10 |
| Math.LOG2E | Base 2 logarithm of E |
| Math.LOG10E | Base 10 logarithm of E |
Math objects: There are many math objects that exist in JavaScript which are listed below:

| atan2(y, x) | Arctangent of the quotient of its arguments |
| ceil(x) | Value of x rounded up to the nearest integer |
| cos(x) | Cosine of x (x in radians) |
| exp() | Value of E^x |
| floor() | Value of x rounded below to the nearest integer |
| log() | Natural logarithm (base E) of x |
| max(a, b, …) | Highest value |
| min(a, b, …) | Lowest value |
| pow(x, y) | Value of x to power of y |
| random() | Random number between 0 and 1 |
| round(x) | Value of x rounded to the nearest integer |
| sin(x) | Sine of x (x in radians) |
| sqrt(x) | Square root of x |
| tan(x) | Tangent of angle |
