VOID FLOATOBJ_SubFloat(
PFLOATOBJ pf, | |
FLOAT f | |
); |
FLOATOBJ_SubFloat subtracts the value of type FLOAT from the FLOATOBJ, and returns the result in the 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.
