Convert any value/type to string callable from C Jul 15, 2022 at 1:27pm ruzip (103) I'm trying to build a C++ function that converts any type to string. ex. int 4 will be "4" float foo with value of 2.5 will be "2.5" .. .. So far I'm using a template like this: ...
When our source is compiled by vs2015, sometimes sprintf may convert float number 0.5 to string “0.0b”, the right string is “0.5”. Most time sprintf seems work correctly,but it may convert the 0.5 to “0.0b” at a percent of 2‰. We have already used _configthreadlo...
We can convert a string to integer in C++ in many ways. To convert a string to integer, we can use stoi() function, atoi() function or stringstream. Methods 1. Convert String to Integer using stoi() To convert a string to integer in C++, you can use stoi() function. The function ...

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...
