Converts the 32-bit integer data with sign specified by s to real number data. The converted data is

stored in d.

This instruction also exists as a P instruction (for FP2/2SH, FP3/5, FP10/10SH PLC types), which

is only executed at the rising edge of the EN trigger. Select [Insert P instruction] from the

"Instructions" pane if you require a P instruction. To facilitate reuse, the instruction then appears

under "Recently used" in the pop-up menu. Press <Ctrl>+<Shift>+<v> within the programming

area to open the list of recently used elements.

Availability of F326_DFLT (see page 1324)

 F326_DFLT cannot be programmed in the interrupt program.

 Instead of using F326_DFLT, you can use variables of the type REAL

with the more flexible instruction DINT_TO_REAL (see page 194).

In this example, the same POU header is used for all programming languages. For an example

using IL (instruction list), please refer to the online help.

All input and output variables used for programming this function have been declared in the POU

When the variable Start is set to TRUE, the double integer value entered for the variable

DINT_input is converted to floating point data, and the result is stored at the address assigned by

the compiler to the variable RealNumberResult. The monitor value icon is activated for both the

LD and IL bodies.
