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 numbers
• float32: single-precision floating-point numbers
• float16: half-precision floating-point numbers
• int32: 32-bit two's complement signed integers
• uint32: 32-bit unsigned integers
• int16: 16-bit two's complement signed integers
• uint16: 16-bit unsigned integers
• int8: 8-bit two's complement signed integers
• uint8: 8-bit unsigned integers
• uint8c: 8-bit unsigned integers clamped to 0-255
• complex128: 128-bit complex numbers
• complex64: 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

s = sizeOf( 'complex64' );
// returns 8
