Expression

Expressions are used to define calculations used for different purposes. They can have variables to allow more advanced configuration.

Constants

• pi - returns ratio of the circumference of a circle to its diameter
• tau - returns ratio of the circumference of a circle to its radius
• e - return the Euler's number

Operators

• x + y - add
• x - y - subtract
• x * y - multiply
• x / y - divided
• x ^ y - exponentiation
• -x - negation
• x & y - and
• x | y - or
• !x - not
• < - less than
• <= - less than or equal
• > - greater than
• >= - greater than or equal
• = - equal
• <> - not equal

Functions

• sin(x) - returns the sine of a number in radians
• cos(x) - returns the cosine of a number in radians
• tan(x) - returns the tangent of a number in radians
• asin(x) - returns the inverse sine (in radians) of a number
• acos(x) - returns the inverse cosine (in radians) of a number
• atan(x) - returns the inverse tangent (in radians) of a number
• sinh(x) - returns the hyperbolic sine of a number
• cosh(x) - returns the hyperbolic cosine of a number
• tanh(x) - returns the hyperbolic tangent of a number
• log(x) - returns the natural logarithm (base e) of a number
• exp(x) - returns e raised to the power of a number
• sqrt(x) - returns the square root of a number
• cbrt(x) - returns the cube root of a number
• floor(x) - returns the largest integer smaller than or equal to the input
• ceil(x) - returns the smallest integer greater than or equal to the input
• round(x) - returns the value of a number rounded to the nearest integer
• trunc(x) - returns the integer part of a number by removing any fractional digits
• abs(x) - returns the absolute value of a number
• sign(x) - returns -1 if the number is less than 0, 1 if the number is greater than 0, and 0 if the number is 0
• fract(x) - returns the fractional part of a number
• mod(x, y) - returns the value of modulo of two numbers
• mix(x, y, t) - returns the linear interpolation between two values
• clamp(x, min, max) - returns a value constrained between two further values
• min(x, y, z, ...) - returns the smallest of the numbers given as input
• max(x, y, z, ...) - returns the largest of the numbers given as input
