Module `core.math`

Builtin mathematical intrinsics

Functions

Name Description

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 * 2^exp

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.

rndtonl(x) Returns x rounded to a long value using the FE_TONEAREST 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.
