     37 ## Usage
     38 
     39 ```javascript
     40 var sameKindCasts = require( '@stdlib/array/same-kind-casts' );
     41 ```
     42 
     43 #### sameKindCasts( \[dtype] )
     44 
     45 If provided a `dtype` argument, returns a list of array [data types][@stdlib/array/dtypes] to which a provided array [data type][@stdlib/array/dtypes] can be safely cast or cast within the same "kind" (e.g., between signed integers or between floating-point numbers).
     46 
     47 ```javascript
     48 var out = sameKindCasts( 'float64' );
     49 // e.g., returns [ 'float64', 'float32', 'generic' ]
     50 ```
     51 
     52 If not provided a `dtype` argument, the function returns a casting table.
     53 
     54 ```javascript
     55 var out = sameKindCasts();
     56 // returns {...}
     57 
     58 var f64 = out[ 'float64' ];
     59 // returns {...}
     60 
     61 var v = f64[ 'float32' ];
     62 // returns 1
     63 ```
     64 
     65 If provided an unrecognized or unsupported `dtype`, the function returns `null`.
     66 
     67 ```javascript
     68 var out = sameKindCasts( 'foo' );
     69 // returns null
     70 ```
