DWORD_TO_REAL

DOUBLE WORD into REAL

DWORD_TO_REAL moves the bit set information of a DWORD variable to a REAL variable. The same functionality can be obtained using DWORD_OVERLAPPING_DUT.

Parameters

Input

Unnamed input (DWORD): input data type

Output

Unnamed output (REAL): Conversion result

Example

POU header

All input and output variables used for programming this function have been declared in the POU header. The same POU header is used for all programming languages.

	VAR
		REAL_value: REAL:=0.0;
		DWORD_value: DWORD:=16#4007F80D;
	END_VAR
