Function
Binary oating-point numbers are rounded to remove the fractional part. The result is stored in D.
M8020 is set when S = 0.
The borrow ag M8021 is set when |S| ≤ 1.
The carry ag M8022 is set if the operation result exceeds either of the following ranges (which results in
an overow):
16-bit instruction: –32,768 to +32,767
32-bit instruction: –2,147,483,648 to +2,147,483,647

S
The floating-point number in (D51, D50) is rounded.
The result is stored in (D100).
The floating-point number in (D11, D10) is rounded.
The result is stored in (D21, D20).
The results of the INT and DINT instructions are stored in
different locations.
