# rint, lrint, llrint

From cppreference.com
< c‎ | numeric‎ | math

Defined in header `<math.h>` |  |
float rintf( float arg ); |  | (since C99)
double rint( double arg ); |  | (since C99)
long double rintl( long double arg ); |  | (since C99)
long lrintf( float arg ); |  | (since C99)
long lrint( double arg ); |  | (since C99)
long lrintl( long double arg ); |  | (since C99)
long long llrintf( float arg ); |  | (since C99)
long long llrint( double arg ); |  | (since C99)
long long llrintl( long double arg ); |  | (since C99)

Rounds the floating-point argument `arg` to an integer value in floating-point format, using the current rounding mode. If the result differs from `arg` (i.e., `arg` was not an integer value already), the floating-point exception FE_INEXACT is raised.

### [edit] Parameters

arg | - | floating point value

### [edit] Return value

The integer result of rounding `arg`

### [edit] Notes

The only difference between nearbyint and rint is that rint may raise the FE_INEXACT floating-point exception, while nearbyint never raises it.

### [edit] Example
