str2enum

Return the enumeration constant associated with an ndarray data type string.

Installation

npm install @stdlib/ndarray-base-dtype-str2enum

Usage

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

str2enum( dtype )

Return the enumeration constant associated with an ndarray data type string.

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

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

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

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

v = str2enum( 'float32' );
// returns <number>

v = str2enum( 'int32' );
// returns <number>

v = str2enum( 'int16' );
// returns <number>

v = str2enum( 'int8' );
// returns <number>

v = str2enum( 'uint32' );
// returns <number>

v = str2enum( 'uint16' );
// returns <number>

v = str2enum( 'uint8' );
// returns <number>
