Javascript mathematical functions and javascript mathematical functions

Javascript mathematical functions are actuallyMath objectIt consists of attributes and functions (or methods. The attributes mainly include the following:

　　 Math. e: E (natural logarithm ),Math. LN2(Natural logarithm of 2 ),Math. LN10(The natural logarithm of 10 ),Math. LOG2E(Logarithm of e, base number 2 ),Math. LOG10E(Logarithm of e, base number is 10 ),Math. PI(π ),Math. SQRT1_2(The square root of 1/2 ),Math. SQRT2(The square root of 2 ).

The following 18 functions are available:

(1)AbsFunction: that is, Math. abs (the same as below), returns the absolute value of a number.

(2)AcosFunction: returns the arc cosine of a number. The result is 0 ~ π radians (radians ).

(3)AsinFunction: returns the arc sine of a number. The result is-π/2 ~ π/2 radian.

(4)AtanFunction: returns the arc tangent of a number. The result is-π/2 ~ π/2 radian.

(5)Atan2Function: returns the Polar Coordinate angle value of a coordinate.

(6)CeilFunction: returns the smallest integer (greater than or equal to) of a number ).

(7)CosFunction: returns the cosine of a number. The result is-1 ~ 1.

(8)ExpFunction: returns the multiplier value of e (natural logarithm.

(9)FloorFunction: returns the maximum integer (less than or equal to) of a number ).

(10)LogFunction: natural logarithm function, which returns the natural logarithm (e) value of a number.

(11)MaxFunction: returns the maximum value of two numbers.

(12)MinFunction: returns the minimum value of two numbers.

(13)PowFunction: returns the multiplier value of a number.

(14)RandomFunction: returns a value ranging from 0 ~ A random value of 1.

(15)RoundFunction: returns the rounding value of a number. The type is an integer.

(16)SinFunction: returns the sine of a number. The result is-1 ~ 1.

(17)SqrtFunction: returns the square root of a number.

(18)TanFunction: returns the tangent of a number.
