VOID FLOATOBJ_Sub(
PFLOATOBJ pf, | |
PFLOATOBJ pf1 | |
); |
FLOATOBJ_Sub subtracts the second FLOATOBJ from the first, and returns the result in the first FLOATOBJ.
The FLOATOBJ_Xxx services allow graphics drivers to emulate floating point arithmetic. Windows NT does not support kernel-mode floating point operations on some systems.
