# SDL_lround

Round `x`

to the nearest integer representable as a long

## Function Parameters

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

## Return Value

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

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

Range: `MIN_LONG <= y <= MAX_LONG`
