Math#
Description#
The math
provides more complicated math functions. Often these
function are just wrappers around the standard C++ functions.
Functions#
hypot : (hypot VALUE)
Compute square root of the sum of the squares of two given numbers.
cbrt : (cbrt VALUE)
Compute cubic root.
fdim : (fdim VALUE)
Compute positive difference of two floating point values.
lgamma : (lgamma VALUE)
Compute the natural logarithm of the gamma function.
pow : (pow VALUE)
Raise a number to the given power.
tgamma : (tgamma VALUE)
Compute the gamma function.
erfc : (erfc VALUE)
Compute the complementary error function.
floor : (floor VALUE)
