Field Descriptions (Continued)
Bit Description Value Field
23 INEX Inexact results status for .M2.
0
1 Result differs from what would have been computed had the exponent range
and precision been unbounded; never set with INVAL.
22 OVER Result overflow status for .M2.
0 Result does not overflow.
1 Result overflows.
21 INFO Signed infinity for .M2.
0 Result is not signed infinity.
1 Result is signed infinity.
20 INVAL
0 A signed NaN (SNaN) is not a source.
1 A signed NaN (SNaN) is a source. NaN is a source in a floating-point to integer
conversion or when infinity is subtracted from infinity.
19 DEN2 Denormalized number select for .M2 src2.
0 src2 is not a denormalized number.
1 src2 is a denormalized number.
18 DEN1 Denormalized number select for .M2 src1.
0 src1 is not a denormalized number.
1 src1 is a denormalized number.
17 NAN2 NaN select for .M2 src2.
0 src2 is not NaN.
1 src2 is NaN.
16 NAN1 NaN select for .M2 src1.
0 src1 is not NaN.
1 src1 is NaN.
