# iterDeg2rad
> Create an [iterator][mdn-iterator-protocol] which converts an angle from degrees to radians for each iterated value.
## Usage
```javascript
var iterDeg2rad = require( '@stdlib/math/iter/special/deg2rad' );
```
#### iterDeg2rad( iterator )
Returns an [iterator][mdn-iterator-protocol] which iteratively converts an angle from degrees to radians.
```javascript
var array2iterator = require( '@stdlib/array/to-iterator' );
var it = iterDeg2rad( array2iterator( [ 90.0, 45.0 ] ) );
// returns
## Notes
- If an iterated value is non-numeric (including `NaN`), the returned [iterator][mdn-iterator-protocol] returns `NaN`. If non-numeric iterated values are possible, you are advised to provide an [`iterator`][mdn-iterator-protocol] which type checks and handles non-numeric values accordingly.
- If an environment supports `Symbol.iterator` **and** a provided [iterator][mdn-iterator-protocol] is iterable, the returned [iterator][mdn-iterator-protocol] is iterable.
## Examples
```javascript
var uniform = require( '@stdlib/random/iter/uniform' );
var iterDeg2rad = require( '@stdlib/math/iter/special/deg2rad' );
// Create a seeded iterator for generating pseudorandom numbers:
var rand = uniform( -360.0, 360.0, {
'seed': 1234,
'iter': 10
});
// Create an iterator which consumes the pseudorandom number iterator:
var it = iterDeg2rad( rand );
// Perform manual iteration...
var v;
while ( true ) {
v = it.next();
if ( v.done ) {
break;
}
console.log( v.value );
}
```
