Calculate hyberbolic arc cosine of number.

Example:

# Example for acosh
println acosh(2.0)

Calculate arc sine of number.

Example:

# Example for asin
println asin(42)

Calculate hyberbolic arc sine of number.

Example:

# Example for asinh
println asinh(1.0)

Calculate arc tangent of number.

Example:

# Example for atan
println atan(42)

Calculate hyberbolic arc tangent of number.

Example:

# Example for atanh
println atanh(42)

Calculate cosine of number.

Example:

# Example for cos
println cos(0.0)

Calculate hyberbolic cosine of number.

Example:

# Example for cosh
println cosh(42)

Convert degrees to radians.

Example:

# Example for deg2rad
println deg2rad(3.14)

Returns the value of e.

Example:

# Example for e
println e()

Round float down to nearest integer.

Example:

# Example for floor
println floor(3.14)

Returns a string holding a conversion of int to base n

Example:
