typemax

    Return the maximum value of a specified numeric type.

    Usage

    var typemax = require( '@stdlib/utils/type-max' );
    

    typemax( dtype )

    Returns the maximum value of a specified numeric type.

    var m = typemax( 'int8' );
    // returns 127
    

    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

    Examples

    var typemax = require( '@stdlib/utils/type-max' );
    
    var m = typemax( 'float64' );
    // returns Infinity
    
    m = typemax( 'float32' );
    // returns Infinity
    
    m = typemax( 'float16' );
    // returns Infinity
    
    m = typemax( 'int32' );
    // returns 2147483647
    
    m = typemax( 'uint32' );
    // returns 4294967295
    
    m = typemax( 'int16' );
    // returns 32767
    
    m = typemax( 'uint16' );
    // returns 65535
    
    m = typemax( 'int8' );
    // returns 127
    
    m = typemax( 'uint8' );
    // returns 255
    
    m = typemax( 'uint8c' );
    // returns 255
