Module core.math
Builtin mathematical intrinsics
Functions
| Name | Description |
|---|---|
cos
|
Returns cosine of x. x is in radians.
|
fabs
|
Returns |x|
|
ldexp
|
Compute n * 2exp
|
rint
|
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
|
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
|
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
|
Returns sine of x. x is in radians.
|
sqrt
|
Compute square root of x.
|
sqrt
|
ditto |
yl2x
|
Building block functions, they translate to a single x87 instruction. |
