The function converts a floating point data at input s in the range -2147483000 to 214783000 into

integer data (including +/- sign). The result of the function is returned at output d.

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

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

value is returned at the output.

When there is a negative floating point value at the input, the next smallest

pre-decimal value is returned at the output.

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

point value 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.
