typemin

    Return the minimum value of a specified numeric type.

    Usage

    var typemin = require( '@stdlib/utils/type-min' );
    

    typemin( dtype )

    Returns the minimum value of a specified numeric type.

    var m = typemin( 'int8' );
    // returns -128
    

    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 typemin = require( '@stdlib/utils/type-min' );
    
    var m = typemin( 'float64' );
    // returns -Infinity
    
    m = typemin( 'float32' );
    // returns -Infinity
    
    m = typemin( 'float16' );
    // returns -Infinity
    
    m = typemin( 'int32' );
    // returns -2147483648
    
    m = typemin( 'uint32' );
    // returns 0
    
    m = typemin( 'int16' );
    // returns -32768
    
    m = typemin( 'uint16' );
    // returns 0
    
    m = typemin( 'int8' );
    // returns -128
    
    m = typemin( 'uint8' );
    // returns 0
    
    m = typemin( 'uint8c' );
    // returns 0
