ceilsd

Round a numeric value to the nearest number toward positive infinity with N significant figures.

Usage

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

ceilsd( x, n[, b] )

Rounds a numeric value to the nearest number toward positive infinity with n significant figures.

var v = ceilsd( Math.PI, 5 );
// returns 3.1416

v = ceilsd( Math.PI, 1 );
// returns 4.0

v = ceilsd( 12368.0, 2 );
// returns 13000.0

The default base is 10 (decimal). To round using a different base, provide a third argument.

var v = ceilsd( 0.0313, 2, 2 );
// returns 0.046875

Examples

var randu = require( '@stdlib/random/base/randu' );
var ceilsd = require( '@stdlib/math/base/special/ceilsd' );

var x;
var y;
var i;

for ( i = 0; i < 100; i++ ) {
    x = (randu()*10000.0) - 5000.0;
    y = ceilsd( x, 5 );
    console.log( 'x: %d. Rounded: %d.', x, y );
