public class RInt
A PostfixMathCommandI which rounds a number to the closest integer.
rint(2.4) finds the closest integer to the argument (2).
rint(2.1234, 3) rounds the argument to 3 decimal places (2.123).
RInt differs from the Round class in that it uses the Math.rint() method rather than Math.round(). Unlike Math.round(), in the case of a tie (e.g 1.5) Math.rint() prefers the nearest even integer (so rint(1.5) = 2). This has better statistical properties.
