Convert an angle from degrees to radians (single-precision).

## Usage

``````var deg2radf = require( '@stdlib/math/base/special/deg2radf' );
``````

Converts an angle from degrees to radians (single-precision).

``````var r = deg2radf( 90.0 );
// returns ~1.571

// returns ~-0.785

// returns NaN
``````

## Examples

``````var randu = require( '@stdlib/random/base/randu' );

var d;
var r;
var i;

for ( i = 0; i < 100; i++ ) {
d = (randu()*720.0) - 360.0;
console.log( 'degrees: %d => radians: %d', d, r );
}
``````

## C APIs

### Usage

``````#include "stdlib/math/base/special/deg2radf.h"
``````

Converts an angle from degrees to radians (single-precision).

``````float y = stdlib_base_deg2radf( 90.0f );
// returns ~1.571f
``````

The function accepts the following arguments:

• x: `[in] float` input value.
``````float stdlib_base_deg2radf( const float x );
``````

### Examples

``````#include "stdlib/math/base/special/deg2radf.h"
#include <stdio.h>

int main() {
float x[] = { 45.0f, 90.0f, 0.0f, 0.0f/0.0f };

float y;
int i;
for ( i = 0; i < 4; i++ ) {
y = stdlib_base_deg2radf( x[ i ] );
printf( "deg2radf(%f) = %f\n", x[ i ], y );
}
}
