The Math.cosh() function returns the hyperbolic cosine of a number,
that can be expressed using the constant e.
The Math.exp() function returns e^x, where x is the argument, and e is Euler’s number
(also known as Napier’s constant), the base of the natural logarithms.
The Math.expm1() function returns e^x - 1, where x is the argument, and e the base of the
natural logarithms.
The Math.floor() function returns the largest integer less than or
equal to a given number.
The Math.fround() function returns the nearest 32-bit single precision float representation
of a Number.
The Math.hypot() function returns the square root of the sum of squares of its arguments.
The Math.imul() function returns the result of the C-like 32-bit multiplication of the

The JavaScript Math.log() function is equivalent to ln(x) in mathematics.
The Math.log1p() function returns the natural logarithm (base e) of 1 + a number.
MDN documentation
The Math.log2() function returns the base 2 logarithm of a number.
The Math.log10() function returns the base 10 logarithm of a number.
The Math.max() function returns the largest of two numbers.
The static function Math.min() returns the lowest-valued number passed into it.
The Math.pow() function returns the base to the exponent power, that is, base^exponent.
The Math.random() function returns a floating-point, pseudo-random number
in the range 0–1 (inclusive of 0, but not 1) with approximately uniform distribution
over that range — which you can then scale to your desired range.
The implementation selects the initial seed to the random number generation algorithm;
it cannot be chosen or reset by the user.
The Math.round() function returns the value of a number rounded to the nearest integer.
The Math.sign() function returns the sign of a number, indicating whether the number is
positive, negative or zero.
The Math.sin() function returns the sine of a number.
The Math.sinh() function returns the hyperbolic sine of a number, that can be expressed
using the constant e: Math.sinh(x) = (e^x - e^-x)/2
The Math.sqrt() function returns the square root of a number, that is
∀x ≥ 0, Math.sqrt(x) = √x = the unique y ≥ 0 such that y^2 = x
The Math.tan() function returns the tangent of a number.
The Math.tanh() function returns the hyperbolic tangent of a number, that is
tanh x = sinh x / cosh x = (e^x - e^-x)/(e^x + e^-x) = (e^2x - 1)/(e^2x + 1)
The Math.trunc() function returns the integer part of a number by removing any fractional
digits.
