Description

Round returns a number that has been rounded to the specified number of decimal places. The required argument, number, is any valid numeric expression. The optional argument, fractionaldigits, is the number of decimal places included in the rounding; if fractionaldigits is not provided it defaults to 0 and Round returns integers.

Example (Basic)

'Round rounds numbers to a given decimal place
Dim Pi, Pure, Ate
Pi = Round(3.14159265, 4)
Print Pi
Pure = Round(99.4444, 2)

Ate = Round(Sqr(69))
Print Ate

Example (JavaScript)

// Round Example
/ *Round rounds numbers to a given decimal place */

function Round(n,d) {
    if (!d || d==null || d=="") {d=0;}
    d=Math.floor(d);
    d=d<1?0:d;
    d=Math.pow(10,d);
    var result=Math.round(n*d) / d;
    return result;
}

var Pi, Pure, Ate;
Pi = Round(3.14159265, 4);
NSB.Print(Pi);
Pure = Round(99.4444, 2);
NSB.Print(Pure);
Ate = Round(Math.sqrt(69));
NSB.Print(Ate);
