varmostlySafeCasts=require('@stdlib/ndarray-mostly-safe-casts');

If provided adtype argument, returns a list of ndarraydata types to which a provided ndarraydata type can be safely cast and, for floating-point data types, can be downcast.

varout=mostlySafeCasts('float32');// e.g., returns [ 'float32', 'float64', ... ]

If not provided adtype argument, the function returns a casting table.

varout=mostlySafeCasts();// returns {...}varf32=out['float32'];// returns {...}varv=f32['float64'];// returns 1

If provided an unrecognized or unsupporteddtype, the function returnsnull.

varout=mostlySafeCasts('foo');// returns null
