Specifies the processor feature to be tested. This value can be one of the following:
| Value | Meaning |
| PF_FLOATING_POINT_PRECISION_ ERRATA |
In rare circumstances, a floating-point precision error can occur (Pentium). |
| PF_FLOATING_POINT_EMULATED | Floating-point operations are emulated using a software emulator. |
