## Usage
38+
39+
```javascript
40+
var resolve = require( '@stdlib/ndarray/base/dtype-resolve-str' );
41+
```
42+
43+
#### resolve( dtype )
44+
45+
Returns the data type string associated with an ndarray data type value.
46+
47+
```javascript
48+
var str2enum = require( '@stdlib/ndarray/base/dtype-str2enum' );
49+
50+
var v = resolve( 'float64' );
51+
// returns 'float64'
52+
53+
v = resolve( str2enum( 'float64' ) );
54+
// returns 'float64'
55+
```
56+
57+
If unable to resolve a data type string, the function returns `null`.
58+
59+
```javascript
60+
var v = resolve( 'beep' );
61+
// returns null
62+
```
