    // returns 2.2250738585072014e-308
    

    The following numeric real types are supported:

    • float64: double-precision floating-point numbers
    • float32: single-precision floating-point numbers
    • float16: half-precision floating-point numbers

    Examples

    var realmin = require( '@stdlib/utils/real-min' );
    
    var m = realmin( 'float64' );
    // returns 2.2250738585072014e-308
    
    m = realmin( 'float32' );
    // returns 1.1754943508222875e-38
    
    m = realmin( 'float16' );
    // returns 0.00006103515625
