5.10.10 INT (FNC 129)
Operation:
The floating point value of S is rounded down to
the nearest integer value and stored in normal
binary format in D.
Points to note:
a) The source data is always a double (32 bit) word; a floating point value.
For single word (16 bit) operation the destination is a 16 bit value.
For double word (32 bit) operation the destination is a 32 bit value.
b) This instruction is the inverse of the FLT instruction. (See page 5-49)
c) If the result is 0 then the zero flag M8020 is set ON.
If the source data is not a whole number it must be rounded down. In this case the borrow
flag M8021 is set ON to indicate a rounded value.
If the resulting integer value is outside the valid range for the destination device then an
overflow occurs. In this case the carry flag M8022 is set on to indicate overflow.
Note: If overflow occurs, the value in the destination device will not be valid.
