Math.exp(x>
Returns ex, with x being the input and e being Euler's constant (2.718..., the natural logarithm's base>
.

Math.expm1(x>
returns the result of subtracting 1 from exp (x>
.

The greatest integer less than or equal to x is returned by Math.floor(x>
.

The closest single precision float representation of x is returned by Math.fround(x>
.

[x[, y[,...]]] Math.hypot([x[, y[,...]]]>
Returns the square root of the sum of its inputs' squares.

Math.imul(x, y>
returns the result of x and y's 32-bit integer multiplication.

Math.log(x>
returns x's natural logarithm (loge; also, ln>

Math.max([x, y,...]]>
The biggest of zero or more numbers is returned.

Math.min([x, y,...]]>
The smallest of zero or more numbers is returned.

arithmetic.pow (x, y>
Returns the exponent power y of base x (that is, xy>
.

Math.random(>
generates a value between 0 and 1 that is pseudo-random.

Math.round(x>
returns the rounded integer value of the number x.

Math.sign(x>
