Nested Class Summary

Nested Classes

Modifier and Type	Class	Description
static final class	MathDoubleExpression.Power	The POWER function takes two numeric arguments and returns a double.
static final class	MathDoubleExpression.Round	The ROUND function takes numeric argument and an integer argument and returns a number of the same type as the first argument.
