Mathematical functions in Javascript

In Javascript, mathematical methods can be divided into the following types:
Constans (constant), power functions (multiplication function), trigonometic functions (trigonometric function), rounding functions (rounding function), random numbers (random number)

Constants and multiplication Functions

Math. E	Base of natural logarithm (constant)	2.718
Math. LN10	Natural logarithm of 10	2.302
Math. LN2	Natural logarithm of 2	0.693
Math. PI	Circumference Rate	3.1415
Math. SQRT1_2	Square root of 1/2	0.707
Math. SQRT2	Square root of 2	1.414
Math. sqrt (x)	Square root of X	It depends on the value of X.
Math. pow (x, n)	Returns the nth power of x.	The parameters are x and n.
Math. log (n)	Returns the natural logarithm of n.	The parameter is n.
Math. exp (n)	Returns the nth power of e.	The parameter is n.

Trigonometric function

Math. cos (x)	Returns the cosine of X.
Math. sin (x)	Sine function of X
Math. tan (x)	Returns the tangent of X.
Math. acos (y)	Returns the arc cosine of X.
Math. asin (y)	Returns the arcsin of X.
Math. atan (y)	Returns the arc tangent function of X.

Note: The unit of the return values of parameter x and inverse functions is radian (for example, PI radian = 180 degrees)

Rounding functions and random numbers

Math. random ()	Generate a random number from 0 to 1
Math. round (x)	Returns the value closest to integer x.
Math. floor (x)	Returns the value closest to integer x and smaller than x.
Math. ceil (x)	Returns the value closest to integer x and greater than x.
Math. min (a, B, c)	Returns the smallest value in the parameter list.
Math. max (a, B, c)	Returns the maximum value in the parameter list.
