# fromWordf
> Create a [single-precision floating-point number][ieee754] from an unsigned integer corresponding to an [IEEE 754][ieee754] binary representation.
## Usage
```javascript
var fromWordf = require( '@stdlib/number/float32/base/from-word' );
```
#### fromWordf( word )
Creates a [single-precision floating-point number][ieee754] from an unsigned `integer` corresponding to an [IEEE 754][ieee754] binary representation.
```javascript
var word = 1068180177; // => 0 01111111 01010110010001011010001
var f32 = fromWordf( word ); // when printed, implicitly promoted to float64
// returns 1.3370000123977661
```
## Notes
- The equivalent of this function in C/C++,
```c
float fromWordf(unsigned int x) {
return *(float*)&x;
}
```
## Examples
```javascript
var randu = require( '@stdlib/random/base/randu' );
var round = require( '@stdlib/math/base/special/round' );
var MAX_UINT32 = require( '@stdlib/constants/uint32/max' );
var fromWordf = require( '@stdlib/number/float32/base/from-word' );
var word;
var f32;
var i;
// Create single-precision floating-point numbers from unsigned integers...
for ( i = 0; i < 1000; i++ ) {
word = round( randu()*MAX_UINT32 );
f32 = fromWordf( word );
console.log( 'word: %d => float32: %d', word, f32 );
}
```

## C APIs
### Usage
```c
#include "stdlib/number/float32/base/from_word.h"
```
#### stdlib_base_float32_from_word( word, \*x )
Creates a [single-precision floating-point number][ieee754] from an unsigned 32-bit integer corresponding to an [IEEE 754][ieee754] binary representation.
```c
#include
uint32_t word = 1078523331;
float x;
stdlib_base_float32_from_word( word, &x );
```
The function accepts the following arguments:
- **word**: `[in] uint32_t` input word.
- **x**: `[out] float*` destination for a single-precision floating-point number.
```c
void stdlib_base_float32_from_word( const uint32_t word, float *x );
```
### Examples
```c
#include "stdlib/number/float32/base/from_word.h"
#include
#include
int main( void ) {
uint32_t word = 1078523331;
float x;
int i;
for ( i = 0; i < 10; i++ ) {
stdlib_base_float32_from_word( word+(uint32_t)(i*10), &x );
printf( "word: %u => %f\n", word, x );
}
}
