com.singularsys.jep.misc.functions
Class Remainder

java.lang.Object
  com.singularsys.jep.functions.PostfixMathCommand
      com.singularsys.jep.functions.BinaryFunction
          com.singularsys.jep.misc.functions.Remainder

All Implemented Interfaces:

PostfixMathCommandI, RealBinaryFunction, java.io.Serializable

public class Remainder
extends BinaryFunction
implements RealBinaryFunction

Calculates the remainder and quotient the arguments. Three different algorithms can be used

• TRUNCATED: q = (int) (x/y), r = x - q y . Remainder has same sign as divisor.
• FLOOR: q = floor(x/y), r = x - q y. Remainder has same sign as dividend.
• EUCLIDEAN: y>0, q = floor(x/y), y<0, ceil(x/y), r = x - q y. Remainder is non negative.

Both arguments are converted to doubles and the the result is a double.
