I found this neat little GUI calculator program on the net.
It uses a function called _gcvt(double val,int limit,string cBuf), which seems to be used to convert a double val to a string cBuf, with some formatting and limiting.
I replaced it with sprintf(), but the output looks rather crude to the perfectionist.
xfind.exe can find _gcvt in a few header files, but Dev C++ does not respond to it. Does anybody have some past experience with it?
