FLOAT expressions return floating point (fractional) numbers. The FLOAT MATH expression performs a floating-point arithmetic operation on two values.

The operation to be performed is supplied in the VALUE attribute of an EXPRNODE element. The values to be operated on are supplied in two sub-expressions.

The possible operations that may be specified in the VALUE attribute are as follows:

The sub-expressions can be PROPERTY, STRING, INTEGER, or FLOAT expressions (use PROPERTY expressions to retrieve values from the current record). The values returned by the sub-expressions are converted to floating-point numbers prior to performing the parent operation.

See the EXPRESSION element for DTD and attribute information.
