lrint, lrintf, lrintl, llrint, llrintf, llrintl — round to nearest integer
||long double x
||long double x
These functions round their argument to the nearest integer value, using the current rounding direction (see fesetround(3)).
Note that unlike the rint(3) family of functions, the return type of these functions differs from that of their arguments.
These functions return the rounded integer value.
x is a NaN or
an infinity, or the rounded value is too large to be stored
in a long (long
long in the case of the
ll* functions), then a domain error occurs,
and the return value is unspecified.
See math_error(7) for information on how to determine whether an error has occurred when calling these functions.
The following errors can occur:
xis a NaN or infinite, or the rounded value is too large
An invalid floating-point exception (
FE_INVALID) is raised.
These functions do not set
