Looking for _gcvt(double,int,string)

[vegaseat]

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?

_gcvt is a Visual Studio function. sprintf should work fine provided you consider limit as the number of significant precision digits.

How appropriately vague. Care to be more specific?

Thanks for the answer!

I will use sprintf(), but need to adjust the precision digits to something sensible.

2.3 + 3.4 = 5.700000000 looks silly!

I had the notion that _gcvt might do this.

You can specify a precision with sprintf:

sprintf ( cBuf, "%.*f", limit, val );

sprintf ( cBuf, "%.*f", limit, val );

I forgot about that, thanks Narue!
