In JavaScript, mathematical methods can be grouped into the following categories:

Constans (constant), power functions (exponentiation function), trigonometic functions (trigonometric function), rounding functions (rounding functions), random numbers (random number)

Reference

Constants and exponentiation functions

MATH.E of the natural logarithm (for constant) 2.718

Natural logarithm of math.ln10 10 2.302

Natural logarithm of MATH.LN2 2 0.693

Math.PI Pi 3.1415

Math.sqrt1_2 1/2 Square root 0.707

Math.sqrt2 2 square root 1.414

MATH.SQRT (x) x has a value for the square root more X

Math.pow (x, N) returns the N-second square of x with a numeric parameter of x and N

Math.log (n) returns the natural logarithm parameter n of n

MATH.EXP (n) returns the N-second side of E with a numeric parameter of n

Trigonometric function

cosine function of Math.Cos (x) x

sine function of Math.sin (x) x

Tangent function of Math.tan (x) x

Inverse cosine function of Math.acos (y) x

Math.asin (y) x's inverse chord function

Inverse tangent function of Math.atan (y) x

Note here: Both the parameter X and the units of the returned values of the inverse function are radians (for example, pi radians = 180 degrees)

Rounding functions and random numbers

Math.random () generates random numbers from 0 to 1

Math.Round (x) takes the nearest integer x value

Math.floor (x) takes the nearest integer x and the number smaller than X

Math.ceil (x) takes the nearest integer x and is larger than X

Math.min (A, B, c) returns the smallest number in the argument list

Math.max (A, B, c) returns the largest number in the argument list
