RINT(3)

NAME
1.48 `rint', `rintf'-round to integer

SYNOPSIS
     #include <math.h>
     double rint(double X);
     float rintf(float X);

DESCRIPTION
The `rint' functions round their argument to an integer value in floating-point format, using the current rounding direction. They raise the "inexact" floating-point exception if the result differs in value from the argument. See the `nearbyint' functions for the same function with the "inexact" floating-point exception never being raised. Newlib does not directly support floating-point exceptions. The `rint' functions are written so that the "inexact" exception is raised in hardware implementations that support it, even though Newlib does not provide access.

RETURNS
X rounded to an integral value, using the current rounding direction.

PORTABILITY
ANSI C, POSIX *See Also*
`nearbyint', `round'
