INT Floating-Point to Integer Conversion
Operation:
Integer(D) D.L (parallel data bus move)
Convert the specified floating-point operand to 32-bit, 2's complement integer. The rounding mode is that
programmed in the SR. The result is stored in the low portion of D. The high and middle portions of D
remain unchanged.
The following table lists the results for some special cases:
Source operand
Greater than 2 31 - 1
Less than -2 31
+infinity
-infinity
NaN
Input Operand(s) Precision: SEP Floating-Point.
Output Operand Precision: 32-bit integer.

$FFFFFFFF
- Not affected.
- Set if source operand is a NaN, infinity, or its magnitude is too big to be represent-
able in the integer number range. Cleared otherwise.
- Set if result is zero. Cleared otherwise.
- Set if source operand is negative. Cleared otherwise.
- Set if source operand is infinity. Cleared otherwise.
- Not affected.
- Not affected.
- Not affected.
-Set if the floating-point operand has no exact integer representation. Cleared oth-
erwise.
-Always cleared.
