8.2 Real Class

The Real Class is used to describe a real scalar or array in the CÆSAR Code Package. The Real Class does not use a user-defined type - it is the class for the F90 intrinsic type ``real''.

Real public procedures:

	Fundamental procedures
	Initialize		Initializes a real scalar or array variable.
	Finalize		Finalizes a real scalar or array variable.
	Valid_State		Returns false iff a real scalar or array variable is in an invalid state.
	Operations
	MaxVal		Extends the F90 intrinsic procedure MaxVal to scalar arguments.
	MinVal		Extends the F90 intrinsic procedure MinVal to scalar arguments.
	SUM		Extends the F90 intrinsic procedure SUM to scalar arguments.
	VeryClose		Returns true if input values are almost equal.

The Real Class code listing contains additional documentation. The Real Class also contains a Unit Test Program.
