    Maximum safe nth Fibonacci number when stored in double-precision floating-point format.

    Installation

    npm install @stdlib/constants-float64-max-safe-nth-fibonacci

    Usage

    var FLOAT64_MAX_SAFE_NTH_FIBONACCI = require( '@stdlib/constants-float64-max-safe-nth-fibonacci' );

    FLOAT64_MAX_SAFE_NTH_FIBONACCI

    The maximum safe nth Fibonacci number when stored in double-precision floating-point format.

    var bool = ( FLOAT64_MAX_SAFE_NTH_FIBONACCI === 78 );
    // returns true

    Examples

    var FLOAT64_MAX_SAFE_NTH_FIBONACCI = require( '@stdlib/constants-float64-max-safe-nth-fibonacci' );
    
    var v;
    var i;
    
    function fibonacci( n ) {
        var a;
        var b;
        var c;
        var i;
    
        a = 1;
        b = 1;
        for ( i = 3; i <= n; i++ ) {
            c = a + b;
            a = b;
            b = c;
        }
        return b;
    }
    
    for ( i = 0; i < 100; i++ ) {
        v = fibonacci( i );
        if ( i > FLOAT64_MAX_SAFE_NTH_FIBONACCI ) {
            console.log( 'Unsafe: %d', v );
        } else {
            console.log( 'Safe:   %d', v );
        }
