Module std.math.exponential

This is a submodule of std.math.

It contains several exponential and logarithm functions.


exp(x) Calculates ex.
exp2(x) Calculates 2x.
expm1(x) Calculates the value of the natural logarithm base (e) raised to the power of x, minus 1.
frexp(value, exp) Separate floating point value into significand and exponent.
ilogb(x) Extracts the exponent of x as a signed integral value.
ldexp(n, exp) Compute n * 2exp
log(x) Calculate the natural logarithm of x.
log10(x) Calculate the base-10 logarithm of x.
log1p(x) Calculates the natural logarithm of 1 + x.
log2(x) Calculates the base-2 logarithm of x: ⊂x
logb(x) Extracts the exponent of x as a signed integral value.
pow(x, n) Compute the value of x n, where n is an integer
pow(x, n) Compute the power of two integral numbers.
pow(x, y) Computes integer to floating point powers.
pow(x, y) Calculates xy.
powmod(x, n, m) Computes the value of a positive integer x, raised to the power n, modulo m.
scalbn(x, n) Efficiently calculates x * 2n.
