The function rounds down the decimal part of the real number data and returns it at output d.

The converted whole-number value at output d is always less than or equal to the floating-point

value at input s:

If a positive floating-point value is at the input, a positive pre-decimal point value

is returned at the output.

If a negative floating-point value is at the input, the next smallest pre-decimal

point value is returned at the output.

If the negative floating-point value has only zeros after the decimal point, its

pre-decimal point position is returned.

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 F333_FINT (see page 1324)

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.
