round() Operation

Syntax	`set aFloat = aFloat.round(base)`
Semantics	Rounds float to a given base. The result is of type Float. If you want to remove the fraction then `base` is 1.0. The common method is implemented: Decide which is the last digit to keep. Increase it by 1, if the next digit is 5 or more (this is called rounding up). Leave it the same, if the next digit is 4 or less (this is called rounding down). See also Rounding on Wikipedia.
Substitutables	`aFloat`	Can be any variable or object attribute having the type Float.
Substitutables	`base`	Is of type Float and encodes the base to be rounded to. For examples, see the table below.
Examples	CODE `set aFloat1 = aFloat1.round(2); set aFloat2 = aFloat3.round(aFloat4);`
