Built-In Mathematical Calculations

Math is a built-in object with properties and methods for mathematical constants and functions. It is not a function object. Math works with the Number type. Math functions are all static, so each starts with Math.myfunctioncallhere(). Math.PI and Math.random() are two Math functions used a lot when doing calculations.

Static methods

Math.abs(): Returns the absolute value of x.
Math.acos(): Returns the arccosine of x.
Math.acosh(): Returns the hyperbolic arccosine of x.
Math.asin(): Returns the arcsine of x.
Math.asinh(): Returns the hyperbolic arcsine of a number.
Math.atan(): Returns the arctangent of x.
Math.atan2(): Returns the arctangent of the quotient of its arguments.
Math.atanh(): Returns the hyperbolic arctangent of x.
Math.cbrt(): Returns the cube root of x.
Math.ceil(): Returns the smallest integer greater than or equal to x.
Math.clz32(): Returns the number of leading zero bits of the 32-bit integer x.
Math.cos(): Returns the cosine of x.
Math.cosh(): Returns the hyperbolic cosine of x.
Math.exp(): Returns e^x, where x is the argument, and e is Euler's number (2.718…, the base of the natural logarithm).
Math.expm1(): Returns subtracting 1 from exp(x).
Math.floor(): Returns the largest integer less than or equal to x.
Math.fround(): Returns the nearest single precision float representation of x.
Math.hypot(): Returns the square root of the sum of squares of its arguments.
Math.imul(): Returns the result of the 32-bit integer multiplication of x and y.
Math.log(): Returns the natural logarithm (㏒_e; also, ㏑) of x.
Math.log10(): Returns the base-10 logarithm of x.
Math.log1p(): Returns the natural logarithm (㏒_e; also ㏑) of 1 + x for the number x.
Math.log2(): Returns the base-2 logarithm of x.
Math.max(): Returns the largest of zero or more numbers.
Math.min(): Returns the smallest of zero or more numbers.
Math.pow(): Returns base x to the exponent power y (that is, x^y).
Math.random(): Returns a pseudo-random number between 0 and 1.
Math.round(): Returns the value of the number x rounded to the nearest integer.
Math.sign(): Returns the sign of the x, indicating whether x is positive, negative, or zero.
Math.sin(): Returns the sine of x.
Math.sinh(): Returns the hyperbolic sine of x.
Math.sqrt(): Returns the positive square root of x.
Math.tan(): Returns the tangent of x.
Math.tanh(): Returns the hyperbolic tangent of x.
Math.trunc(): Returns the integer portion of x, removing any fractional digits.
