Here is where my confusion comes from. I created a simple app to
test NewFloatMgr. So I created a couple of floats and added them, using
NewFloatMgr functions. Everything was fine.
Then I deleted the #include NewFloatMgr.h line and deleted all my
NewFloatMgr functions and declarations. Then I just declared two more
variables of double and two of float. I then added these like:
fp1 = fp2 + fp3; worked fine, compiled fine.
So, I am confused about why NewFloatMgr is even necessary. I verified
that I don't have some hidden include to NewFloatMgr by using some
NewFloatMgr functions and the compile errors showed up without the
include.
So, if I can declare a type of double or float and add these numbers
as above, why is NewFloatMgr even necessary. At first I thought it was
because there was no float or double type but that does not seem to be
the case.
BTW, I am using gcc not CW.
