Assembler Syntax:
FINT S,D (move syntax - see the MOVE instruction de-
scription.)
Description:
Round the floating-point source operand S to an integer value using the current rounding mode specified
by bits R1-R0 in the IER register, and store the result as a floating-point number in the specified destination
D. The rounding precision is always SEP. For example: if the rounding is to +
∞,
then 110.50 rounds to
111.00; however if the rounding is to 0, -
∞
, or even, then 110.50 rounds to 110.0.
Input Operand(s) Precision: SEP Floating-Point.
Output Operand Precision: SEP Floating-Point.
CCR Condition Codes:

Z
- Set if result is zero. Cleared otherwise.
N
- Set if result is negative. Cleared otherwise.
I
- Set if result is infinity. Cleared otherwise.
LR
- Not affected.

-Set if result is inexact. Cleared otherwise.
DZ
-Always cleared.
UNF
-Always cleared.
OVF
-Always cleared.
OPERR-Always cleared.
SNAN -Set if operand is a signaling NaN. Cleared otherwise.
NAN
-Set if result is a NaN. Cleared otherwise.
UNCC -Always cleared.
IER Flags: Flags changed according to standard definition.
