Classic Math Functions

Putting the fun back in function.

Roots

Function

Name

Behaviour

sqrt()

Square Root

Returns the square root of a number (also √)

cbrt()

Cubed Root

Returns the cubed root of a number

Exponential and Logarithms

Function

Name

Behaviour

exp()

Exponential

Calculates the value of e to the power of x, where e is the base of the natural logarithm. exp(1) returns Euler's number.

ln()

Natural logarithm

The natural logarithm of a number is its logarithm to the base of the mathematical constant e.

log2()

Base 2 logarithm

Calculate the base 2 logarithm of a value

log(), log10()

Base 10 logarithm

Calculate the base 10 logarithm of a value

Rounding

Function

Name

Behaviour

round()

Integer round

Rounds a number to the nearest integer

ceil()

Ceiling

Rounds a number up to the nearest whole number

floor()

Floor

Rounds a number down to the nearest whole number

Trigonometry

Function

Name

sin()

Calculate the sine of a value

sinh()

Calculate the hyperbolic sine of a value

asin()

Calculate the inverse sine of a value

asinh()

Calculate the hyperbolic arcsine of a value

cos()

Calculate the cosine of a value

cosh()

Calculate the hyperbolic cosine of a

acos()

Calculate the inverse cosine of a value

acosh()

Calculate the hyperbolic arccos of a value

tan()

Calculate the tangent of a value

tanh()

Calculate the hyperbolic tangent of a value

atan()

Calculate the inverse tangent of a value

atanh()

Calculate the hyperbolic arctangent of a value

Trigonometric functions assume a value in radians by default. If you want to use degrees, specify this in the parameter:

sin(90 degrees) // 1.0

sin(90) // 0.8939966636
