math/abs cfunction
(math/abs x) Return the absolute value of x.
math/acos cfunction
(math/acos x) Returns the arccosine of x.
math/asin cfunction
(math/asin x) Returns the arcsine of x.
math/atan cfunction
(math/atan x) Returns the arctangent of x.
math/atan2 cfunction
(math/atan2 y x) Return the arctangent of y/x. Works even when x is 0.
math/ceil cfunction
(math/ceil x) Returns the smallest integer value number that is not less than x.
math/cos cfunction
(math/cos x) Returns the cosine of x.
math/cosh cfunction
(math/cosh x) Return the hyperbolic cosine of x.
math/e number
The base of the natural log.
math/exp cfunction
(math/exp x) Returns e to the power of x.
math/floor cfunction
(math/floor x) Returns the largest integer value number that is not greater than x.
math/inf number
The number representing positive infinity
math/log cfunction
(math/log x) Returns log base natural number of x.
math/log10 cfunction
(math/log10 x) Returns log base 10 of x.
math/pi number
The value pi.
math/pow cfunction
(math/pow a x) Return a to the power of x.
math/random cfunction
(math/random) Returns a uniformly distributed random number between 0 and 1.
math/rng cfunction
(math/rng &opt seed) Creates a Psuedo-Random number generator, with an optional seed. The seed should be an unsigned 32 bit integer. Do not use this for cryptography. Returns a core/rng abstract type.
math/rng-int cfunction
(math/rng-int rng &opt max) Extract a random random integer in the range [0, max] from the RNG. If no max is given, the default is 2^31 - 1.
math/rng-uniform cfunction
(math/rng-seed rng seed) Extract a random number in the range [0, 1) from the RNG.
math/seedrandom cfunction
(math/seedrandom seed) Set the seed for the random number generator. 'seed' should be an integer.
math/sin cfunction
(math/sin x) Returns the sine of x.
math/sinh cfunction
(math/sinh x) Return the hyperbolic sine of x.
math/sqrt cfunction
(math/sqrt x) Returns the square root of x.
math/tan cfunction
(math/tan x) Returns the tangent of x.
math/tanh cfunction
(math/tanh x) Return the hyperbolic tangent of x.
