cos alias cos = llvm_cos!float

Returns cosine of x. x is in radians.

cos alias cos = llvm_cos!double

Returns cosine of x. x is in radians.

cos alias cos = llvm_cos!real

Returns cosine of x. x is in radians.

fabs alias fabs = llvm_fabs!float

Compute the absolute value.

Special Values
x	fabs(x)
±0.0	+0.0
±∞	+∞

It is implemented as a compiler intrinsic.

fabs alias fabs = llvm_fabs!double

Compute the absolute value.

Special Values
x	fabs(x)
±0.0	+0.0
±∞	+∞

It is implemented as a compiler intrinsic.

fabs alias fabs = llvm_fabs!real

Compute the absolute value.

Special Values
x	fabs(x)
±0.0	+0.0
±∞	+∞

It is implemented as a compiler intrinsic.

rint alias rint = llvm_rint!float

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.

rint alias rint = llvm_rint!double

rint alias rint = llvm_rint!real

rndtol alias rndtol = llroundf

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.

rndtol alias rndtol = llround

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.

rndtol alias rndtol = llroundl

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 alias sin = llvm_sin!float

Returns sine of x. x is in radians.

sin alias sin = llvm_sin!double

Returns sine of x. x is in radians.

sin alias sin = llvm_sin!real

Returns sine of x. x is in radians.
