Module core.math

Builtin mathematical intrinsics

Functions

NameDescription
cos(x) Returns cosine of x. x is in radians.
fabs(x) Compute the absolute value.
Special Values
x fabs(x)
±0.0 +0.0
±∞ +∞
It is implemented as a compiler intrinsic.
fabs(x) ditto
ldexp(n, exp) Compute n * 2exp
rint(x) Rounds x to the nearest integer value, using the current rounding mode. If the return value is not equal to x, the FE_INEXACT exception is raised. nearbyint performs the same operation, but does not set the FE_INEXACT exception.
rndtol(x) Returns x rounded to a long value using the current rounding mode. If the integer value of x is greater than long.max, the result is indeterminate.
sin(x) Returns sine of x. x is in radians.
sqrt(x) Compute square root of x.
toPrec(f) Round argument to a specific precision.
yl2x(x, y) Building block functions, they translate to a single x87 instruction.
yl2xp1(x, y) Building block functions, they translate to a single x87 instruction.
