# SDL_scalbnf

Scale `x` by an integer power of two.

## Header File

Defined in [<SDL3/SDL_stdinc.h>](https://github.com/libsdl-org/SDL/blob/main/include/SDL3/SDL_stdinc.h)

## Syntax

```c
float SDL_scalbnf(float x, int n);

```

## Function Parameters

|           |                                   |
| --------- | --------------------------------- |
| **x**     | floating point value to be scaled |
| **n**     | integer exponent                  |

## Return Value

Returns `x * 2^n`

## Remarks

Multiplies `x` by the `n`th power of the floating point radix (always 2).

Domain: `-INF <= x <= INF`, `n` integer

Range: `-INF <= y <= INF`

This function operates on single-precision floating point values, use
[SDL_scalbn](SDL_scalbn) for double-precision floats.

## Version

This function is available since SDL 3.0.0.
