    ceil10

    NPM version Build Status Coverage Status dependencies

    Round a numeric value to the nearest power of 10 toward positive infinity.

    Installation

    npm install @stdlib/math-base-special-ceil10

    Usage

    var ceil10 = require( '@stdlib/math-base-special-ceil10' );

    ceil10( x )

    Rounds a numeric value to the nearest power of 10 toward positive infinity.

    var v = ceil10( -4.2 );
    // returns -1.0
    
    v = ceil10( -4.5 );
    // returns -1.0
    
    v = ceil10( -4.6 );
    // returns -1.0
    
    v = ceil10( 9.99999 );
    // returns 10.0
    
    v = ceil10( 9.5 );
    // returns 10.0
    
    v = ceil10( 13.0 );
    // returns 100.0
    
    v = ceil10( -13.0 );
    // returns -10.0
    
    v = ceil10( 0.0 );
    // returns 0.0
    
    v = ceil10( -0.0 );
    // returns -0.0
    
    v = ceil10( Infinity );
    // returns Infinity
    
    v = ceil10( -Infinity );
    // returns -Infinity
    
    v = ceil10( NaN );
    // returns NaN

    Notes

    • The function may not return accurate results for subnormals due to a general loss in precision.

      var v = ceil10( -1.0e-323 ); // should return -1.0e-323
      // returns -0.0

    Examples

    var randu = require( '@stdlib/random-base-randu' );
    var ceil10 = require( '@stdlib/math-base-special-ceil10' );
    
    var x;
    var v;
    var i;
    
    for ( i = 0; i < 100; i++ ) {
        x = (randu()*100.0) - 50.0;
        v = ceil10( x );
        console.log( 'Value: %d. Rounded: %d.', x, v );
    }
