sizeOf
Return the size (in bytes) of the canonical binary representation of a specified numeric type.
Usage
var sizeOf = require( '@stdlib/utils/size-of' );
sizeOf( dtype )
Returns the size (in bytes) of the canonical binary representation of a specified numeric type.
var s = sizeOf( 'int8' );
// returns 1
The following numeric types are supported:
float64: double-precision floating-point numbersfloat32: single-precision floating-point numbersfloat16: half-precision floating-point numbersint32: 32-bit two's complement signed integersuint32: 32-bit unsigned integersint16: 16-bit two's complement signed integersuint16: 16-bit unsigned integersint8: 8-bit two's complement signed integersuint8: 8-bit unsigned integersuint8c: 8-bit unsigned integers clamped to0-255complex128: 128-bit complex numberscomplex64: 64-bit complex numbers
Examples
var sizeOf = require( '@stdlib/utils/size-of' );
var s = sizeOf( 'float64' );
// returns 8
s = sizeOf( 'float32' );
// returns 4
s = sizeOf( 'float16' );
// returns 2
s = sizeOf( 'int32' );
// returns 4
s = sizeOf( 'uint32' );
// returns 4
s = sizeOf( 'int16' );
// returns 2
s = sizeOf( 'uint16' );
// returns 2
s = sizeOf( 'int8' );
// returns 1
s = sizeOf( 'uint8' );
// returns 1
s = sizeOf( 'uint8c' );
// returns 1
s = sizeOf( 'complex128' );
// returns 16
