# SDL_lround
Round `x` to the nearest integer representable as a long
## Header File
Defined in [](https://github.com/libsdl-org/SDL/blob/main/include/SDL3/SDL_stdinc.h)
## Syntax
```c
long SDL_lround(double x);
```
## Function Parameters
| | | |
| ------ | ----- | --------------------- |
| double | **x** | floating point value. |
## Return Value
(long) Returns the nearest integer to `x`.
## Remarks
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](SDL_lround) for single-precision floats. To get the result as
a floating-point type, use [SDL_round](SDL_round).
## Thread Safety
It is safe to call this function from any thread.
## Version
This function is available since SDL 3.0.0.
