Suppose you have a constant floating-point number, and you want to convert it into a string using preprocessor macros. Here’s how you can do it: #include<iostream>#include<string>using std::cout;using std::endl;using std::string;#defineSTRINGIFY_FLOAT(x) #xintmain(){string num_str=ST...

Hi, guys. I am having trouble converting numbers (which is in String datatype) into float or double. I need to add these numbers and return the sum of it to 2 decimal points. I know this is quite easy but I have search in quite a lot of info but don't know exactly how to use...
The tests used in that library for string to double/float conversion are a little more extensive. At the end of the article a number of comparisons between, stdlib, Boost, Spirit and StrTk can be found using various hardware configurations/compilers etc. http://www.codeproject.com/KB/recipes...
