    sizeOf

    NPM version Build Status Coverage Status dependencies

    Return the size (in bytes) of the canonical binary representation of a specified numeric type.

    Installation

    npm install @stdlib/utils-size-of

    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
