rint
(), rintf
(), and
rintl
() functions return the integral value nearest to
x according to the prevailing rounding mode. These
functions raise an inexact exception when the original argument is not an
exact integer.
The nearbyint
(),
nearbyintf
(), and
nearbyintl
() functions perform the same operation,
except that they do not raise an inexact exception.
