Hi guys,
I have been trying to learn win32 asm programming from Iczelions site...and I am having a couple of problems with something I'm trying to write.
Basically, I've made it to about the 9th tut which involves using child window controls (buttons and edit boxes and such). I am using an edit box to get a numerical string from the user which I am want to convert into a floating point number using the StrToFloat function. Then after some calculations are performed on the floating point number, the press of a button will output it again as a string in a message box. Here is my problem...
The floating point number output by the StrToFloat function is an 8 byte QWORD and I can't figure out how to add / subtract / multiply / divide with this size of value. I have looked at an assembly reference book and can find no instructions for dealing with this size (it is an old book so possibly it doesn't contain all of the instructions). Any help will be appreciated.
Thanks in advance...
Regards :-)
