Signaling-Computational Operations Functions

Many routines in the
libbfp754
Library are more optimized for Intel® microprocessors than for non-Intel microprocessors.
The Intel® IEEE 754-2008 Binary Conformance Library supports the following functions for signaling-computational operations:

quiet_equal

Description:
The function returns
1
(true) if the relation between the two inputs
x
and
y
is equal, returns
0
(false) otherwise. The function signals invalid operation exception when signaling
NaN
is in the inputs.
Calling interface:
int __binary32_quiet_equal_binary32 (float x, float y);
int __binary32_quiet_equal_binary64(float x, double y);
int __binary64_quiet_equal_binary32(double x, float y);
int __binary64_quiet_equal_ binary64(double x, double y);

quiet_not_equal

Description:
The function returns
1
(true) if the relation between the two inputs
x
and
y
is not equal, returns
0
(false) otherwise. The function signals invalid operation exception when signaling
NaN
is one of the inputs.
Calling interface:
int __binary32_quiet_not_equal_binary32(float x, float y);
int __binary32_quiet_not_equal_binary64(float x, double y);
int __binary64_quiet_not_equal_binary32(double x, float y);
int __binary64_quiet_not_equal_binary64(double x, double y);

signaling_equal

Description:
The function returns
1
(true) if the relation between the two inputs
