If it is less than 0. To extend the Math object, you do not use prototype. Returns the cube root of a number. Returns the sign of the x, indicating whether x is positive, negative or zero. Returns subtracting 1 from exp x. Description Because abs is a static method of Math, you always use it as Math. Description Because ceil is a static method of Math, you always use it as Math.

Returns the arccosine of a number. Properties Euler's constant and the base of natural logarithms, approximately 2. Because round is a static method of Math, you always use it as Math. Returns the natural logarithm log e, also ln of a number. Returns the number of leading zeroes of a 32-bit integer. Return value The value of the given number rounded to the nearest integer. The source for this interactive example is stored in a GitHub repository.

Instead, you directly extend Math: Math. Standard Standard Draft Browser compatibility The compatibility table in this page is generated from structured data. Natural logarithm of 10, approximately 2. You refer to the constant pi as Math. Returns the base 10 logarithm of a number.

Returns the base 2 logarithm of a number. Returns the hyperbolic arccosine of a number. Math is a built-in object that has properties and methods for mathematical constants and functions. Standard Standard Draft Browser compatibility The compatibility table in this page is generated from structured data. Returns the hyperbolic arctangent of a number. Note that this differs from many languages' round functions, which often round this case to the next integer away from zero, instead giving a different result in the case of negative numbers with a fractional part of exactly 0. Returns the largest of zero or more numbers.
