INTU
Floating-Point
INTU
to Unsigned Integer Conversion
Operation:
Unsigned Integer(D)
→
D.L
(parallel data bus move)
Assembler Syntax:
INTU D
(move syntax - see the Move instruction description.)
Description:
Convert the specified floating-point operand to 32-bit, unsigned integer. The rounding mode is that spec-
ified in the SR. The result is stored in the low portion of D. The high and middle portions of D remain un-
changed.
The following table lists the results for some special cases:
Source operand
Result
Greater than 2
31
- 1
$7FFFFFFF
Less than -2
31
$80000000
+infinity
$7FFFFFFF
-infinity
$80000000
NaN
$FFFFFFFF
+/- Zero
$00000000
Input Operand(s) Precision: SEP Floating-Point.
Output Operand Precision: 32-bit integer.
CCR Condition Codes:
C
- Not affected.
V
- Set if source operand is a NaN, infinity or negative non-zero. Set if positive source
operand is too big to be representable in the integer number range. Cleared oth-
erwise.
Z
- Set if result is zero. Cleared otherwise.
N
- Set if source operand is negative. Cleared otherwise.
I
- Set if source operand is infinity. Cleared otherwise.
LR
- Not affected.

R
- Not affected.
A
