Math Object (JavaScript)

JavaScript - Internet Explorer 10

An intrinsic object that provides basic mathematics functionality and constants.

Math.[{property | method}]

Parameters

property: Required. Name of one of the properties of the Math. object.
method: Required. Name of one of the methods of the Math. object.

Remarks

The Math object cannot be created using the new operator, and gives an error if you attempt to do so. The scripting engine creates it when the engine is loaded. All of its methods and properties are available to your script at all times.

Requirements

The Math object was introduced in Internet Explorer before Internet Explorer 6.

Constants

The following table lists the constants of the Math object.

Constant	Description
Math.E Constant	The mathematical constant e. This is Euler's number, the base of natural logarithms.
Math.LN2 Constant	The natural logarithm of 2.
Math.LN10 Constant	The natural logarithm of 10.
Math.LOG2E Constant	The base-2 logarithm of e.
Math.LOG10E Constant	The base-10 logarithm of e.
Math.PI Constant	Pi. This is the ratio of the circumference of a circle to its diameter.
Math.SQRT1_2 Constant	The square root of 0.5, or, equivalently, one divided by the square root of 2.
Math.SQRT2 Constant	The square root of 2.

Functions

The following table lists the functions of the Math object.

Function	Description
Math.abs Function	Returns the absolute value of a number.
Math.acos Function	Returns the arccosine of a number.
Math.asin Function	Returns the arcsine of a number.
Math.atan Function	Returns the arctangent of a number.
Math.atan2 Function	Returns the angle (in radians) from the X axis to a point represented by the supplied y and x coordinates.
Math.ceil Function	Returns the smallest integer that is greater than or equal to the supplied numeric expression.
Math.cos Function	Returns the cosine of a number.
Math.exp Function	Returns e (the base of natural logarithms) raised to a power.
Math.floor Function	Returns the greatest integer that is less than or equal to the supplied numeric expression.
Math.log Function	Returns the natural logarithm of a number.
Math.max Function	Returns the greater of two supplied numeric expressions.
Math.min Function	Returns the lesser of two supplied numbers.
Math.pow Function	Returns the value of a base expression raised to a specified power.
Math.random Function	Returns a pseudorandom number between 0 and 1.
Math.round Function	Returns a specified numeric expression rounded to the nearest integer.
