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.
Parameters
pf
Pointer to the FLOATOBJ operand. The result of pf minus f is returned in this parameter.
f
The FLOAT operand. This value is converted to a FLOATOBJ for the subtraction.
Comments
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.
