(math/atan2 y x)
Returns the arctangent of y/x. Works even when x is 0.
(math/atanh x)
Returns the hyperbolic arctangent of x.
(math/ceil x)
Returns the smallest integer value number that is not less than x.
(math/erfc x)
Returns the complementary error function of x.
(math/floor x)
Returns the largest integer value number that is not greater than x.
(math/frexp x)
Returns a tuple of (mantissa, exponent) from number.
(math/gcd x y)
Returns the greatest common divisor between x and y.
(math/hypot a b)
Returns c from the equation c^2 = a^2 + b^2.
The maximum contiguous integer representable by a double (-(2^53))
The minimum contiguous integer representable by a double (2^53)
The maximum contiguous integer representable by a 32 bit signed integer
The minimum contiguous integer representable by a 32 bit signed integer
(math/lcm x y)
Returns the least common multiple of x and y.
(math/ldexp m e)
Creates a new number from a mantissa and an exponent.
(math/log1p x)
Returns (log base e of x) + 1 more accurately than (+ (math/log x) 1)
(math/next x y)
Returns the next representable floating point value after x in the direction of y.
(math/random)
Returns a uniformly distributed random number between 0 and 1.
(math/rng &opt seed)
Creates a Pseudo-Random number generator, with an optional seed. The seed should be an unsigned 32 bit integer or a buffer. Do not use this for cryptography. Returns a core/rng abstract type.
(math/rng-buffer rng n &opt buf)
Get n random bytes and put them in a buffer. Creates a new buffer if no buffer is provided, otherwise appends to the given buffer. Returns the buffer.
(math/rng-int rng &opt max)
Extract a random integer in the range [0, max) for max > 0 from the RNG. If max is 0, return 0. If no max is given, the default is 2^31 - 1.
(math/rng-uniform rng)
Extract a random number in the range [0, 1) from the RNG.
(math/seedrandom seed)
Set the seed for the random number generator. seed should be an integer or a buffer.
(math/trunc x)
Returns the integer between x and 0 nearest to x.
