# SDL_lround

Round `x`

to the nearest integer representable as a long

Defined in <SDL3/SDL_stdinc.h>

## Syntax

`long SDL_lround(double x);`

## Function Parameters

double |
**x** |
floating point value. |

## Return Value

(long) Returns the nearest integer to `x`

.

Rounds `x`

to the nearest integer. Values halfway between integers will be rounded away from zero.

Domain: `-INF <= x <= INF`

Range: `MIN_LONG <= y <= MAX_LONG`

This function operates on double-precision floating point values, use SDL_lround for single-precision floats. To get the result as a floating-point type, use SDL_round.

## Thread Safety
