TRSFMXCustomChartFunction.GreatestCommonDivisor(TRSCustomChart,TRSCustomChart,Integer,Integer,TDateTime,Integer,Integer) Method

Scroll Prev Top Next More

Calculates the greatest common divisor (gcd) of the SourceChart Values and adds the GCD to the TargetChart. The SourceChart Values are rounded into integers and the GCD calculated from this array. The GCD of two or more integers, when at least one of them is not zero, is the largest positive integer that divides the numbers without a remainder. For example, the GCD of 8 and 12 is 4.

If the TargetChart is of a type that has more than 2 dimensions, such as a TRSLineChart with X and Y values, the new TargetChart value includes the TimeStamp.
