Values
namespace Math
acos
Type: Std::F64 -> Std::F64
Calculates arc cosine of the argument.
This is wrapper of C's acos.
asin
Type: Std::F64 -> Std::F64
Calculates arc sine of the argument.
This is wrapper of C's asin.
atan
Type: Std::F64 -> Std::F64
Calculates arc tangent of the argument.
This is wrapper of C's atan.
atan2
Type: Std::F64 -> Std::F64 -> Std::F64
atan2(y, x) calculates an angle t such that (cos(t), sin(t)) is parallel to (x, y).
This is wrapper of C's atan2.
binomial_coefficients
Type: Std::I64 -> Std::Array (Std::Array Std::I64)
Calculates table (2-dimensional array) of binomial coefficients.
Deprecated: this function will be moved to another project in the future.
binomial_coefficients(m) evaluates to an array of arrays table where table.@(n).@(r) is the binomial coefficient "binom(n, r)" for 0 <= n <= m and 0 <= r <= n.
Here m has to be less than or equal to 66 to avoid overflow.

This is wrapper of C's ceil.
cos
Type: Std::F64 -> Std::F64
Calculates the cosine of the argument.
This is wrapper of C's cos.
cosh
Type: Std::F64 -> Std::F64
Calculates the hyperbolic cosine of the argument.
This is wrapper of C's cosh.
e32
Type: Std::F32
Napier's constant as F32
e64
Type: Std::F64
Napier's constant as F64
exp
Type: Std::F64 -> Std::F64
Calculates the natural exponential of the argument.
This is wrapper of C's exp.
floor
Type: Std::F64 -> Std::F64
Calculates the largest integral value not greater than the argument.
This is wrapper of C's floor.
fmod
Type: Std::F64 -> Std::F64 -> Std::F64
Calculates the floating point remainder of division.
x.fmod(y) evaluates to the remainder of dividing x by y.
This is wrapper of C's fmod.
frexp
Type: Std::F64 -> (Std::F64, Std::I32)
Splits a floating point number to normalized fraction and an exponent.
This is wrapper of C's frexp.
gcd
Type: Std::I64 -> Std::I64 -> Std::I64
Calculates greatest common divisor of two integers. Deprecated: this function will be moved to another project in the future.
NOTE: currently, this function does not support I64::minimum.
ldexp
Type: Std::I32 -> Std::F64 -> Std::F64
Multiplies a floating point number by power of two.
This is wrapper of C's ldexp.
log
Type: Std::F64 -> Std::F64
Calculates natural logarithm.
This is wrapper of C's log.
log10
Type: Std::F64 -> Std::F64
Calculates base-10 logarithm.
This is wrapper of C's log10.
modf
Type: Std::F64 -> (Std::F64, Std::F64)
Converts a floating pointer number into the pair of fractional part and integral part.
This is wrapper of C's modf.
pi32
Type: Std::F32
pi as F32
pi64
Type: Std::F64
pi as F64

This is wrapper of C's sinh.
sqrt
Type: Std::F64 -> Std::F64
Calculates square root of the argument.
This is wrapper of C's sqrt.
tan
Type: Std::F64 -> Std::F64
Calculates the tangent of the argument.
This is wrapper of C's tan.
