BitConverter.HalfToInt16Bits(Half) result comparison issue #82680
Description
Description
I am playing around the negative zero number and I found an interesting thing while I used BitConverter.HalfToInt16(Half) method.
The two comparison gives different result
- Compare the method result directly to 0.
- Store the method result in a
shortvariable then compare the variable to 0.
Reproduction Steps
Half half = (Half)(-0.0f);
// It will be -32768.
short bits = BitConverter.HalfToInt16Bits(half);
// It will be true.
bool isMethodResultGreaterThanOrEqualToZero = BitConverter.HalfToInt16Bits(half) >= 0;
// It will be false.
bool isVariableGreaterThanOrEqualToZero = bits >= 0;Expected behavior
The expected behavior is that the two comparison method should have the same result: false
Actual behavior
- When directly check if the method result is
>= 0then the comparison result will betrue. - When storing the method result first in a variable and then check if the variable is
>= 0then the comparison result will befalse.
