resolve

Return the enumeration constant associated with a supported ndarray data type value.

Usage

var resolve = require( '@stdlib/ndarray/base/dtype-resolve-enum' );

resolve( dtype )

Returns the enumeration constant associated with an ndarray data type value.

var str2enum = require( '@stdlib/ndarray/base/dtype-str2enum' );

var v = resolve( 'float64' );
// returns <number>

v = resolve( str2enum( 'float64' ) );
// returns <number>

If unable to resolve an enumeration constant, the function returns null.

var v = resolve( 'beep' );
// returns null

Notes

Downstream consumers of this function should not rely on specific integer values (e.g., INT8 == 0). Instead, the function should be used in an opaque manner.

Examples

var resolve = require( '@stdlib/ndarray/base/dtype-resolve-enum' );

var v = resolve( 'float64' );
// returns <number>

v = resolve( 'float32' );
// returns <number>

v = resolve( 'int32' );
// returns <number>

v = resolve( 'int16' );
// returns <number>

v = resolve( 'int8' );
// returns <number>

v = resolve( 'uint32' );
// returns <number>

v = resolve( 'uint16' );
// returns <number>

v = resolve( 'uint8' );
// returns <number>
