WMLScript > Float > round()

round() - The round function

Usage:

round(value)

Description: Returns the number value that is closest to the given value and is equal to a mathematical integer. If two integer number values are equally close to the value, the result is the larger integer value. If the value is already an integer, the result is the value itself.

Example:

var a = Float.round(3.5);    // a = 4
var b = Float.round(-3.5);   // b = -3;
var c = Float.round(0.5);    // c = 1
var d = Float.round(-0.5);   // d = 0
