They provide a consistent output unlike snprintf() which depends on the current locale.
Sample code below:īoth work for all int including INT_MIN. *ptr++ = "zyxwvutsrqponmlkjihgfedcba9876543210123456789abcdefghijklmnopqrstuvwxyz" Ĭonverting anything to a string should either 1) allocate the resultant string or 2) pass in a char * destination and size. Since the link above is either off-line or no longer active, I've included their 4th version below: /**Ĭhar* itoa(int value, char* result, int base) Ĭhar* ptr = result, *ptr1 = result, tmp_char How can I accomplish this, and yes my int has to be unsigned. I tried strcpy, sprintf, i looked through the help endlessly, googled it. I have an unsigned int, that has the data i want to put into a string.
While sprintf/ snprintf have advantages, they will not handle negative numbers for anything other than decimal conversion. Below is a stripped down function of essentialy what I am trying to do. P format using es-ES culture: 167.After having looked at various versions of itoa for gcc, the most flexible version I have found that is capable of handling conversions to binary, decimal and hexadecimal, both positive and negative is the fourth version found at. Most reasons for using the C++ part on a M is that all the fancy libs & examples are in C++. P format using fr-FR culture: 167 900,00 % -304 500,00 % M VC is a C++ compiler, but can do regular C, as others. G format using es-ES culture: 1679 -3045
G format using fr-FR culture: 1679 -3045 G format using en-US culture: 1679 -3045 This example displays the following output to the console: The example displays the following output:Ĭonsole.WriteLine(value.ToString(CultureInfo.InvariantCulture)) Ĭonsole.WriteLine(value.ToString(CultureInfo.CreateSpecificCulture("en-GB"))) Ĭonsole.WriteLine(value.ToString(CultureInfo.CreateSpecificCulture("de-DE"))) Display value using the de-DE culture.Ĭonsole::WriteLine(value.ToString(CultureInfo::CreateSpecificCulture("de-DE")))
Display value using the en-GB culture.Ĭonsole::WriteLine(value.ToString(CultureInfo::CreateSpecificCulture("en-GB"))) Display value using the invariant culture.Ĭonsole::WriteLine(value.ToString(CultureInfo::InvariantCulture)) The following example displays the string representation of an Int32 value using CultureInfo objects that represent several different cultures.
