Character Manipulation Function

char *qgcvt(long double value, int ndigit, int *decpt, int *neg);

Internationalization (I18n) Function Overview

This function is equivalent to gcvt except that it takes a long double for the first parameter and that ndigit is restricted by the precision of a long double.

I18n Issues

qgcvt should not be used for strings that will be displayed to the user because the decimal separator and the position of the sign byte are not dependent on the numeric settings of the user's locale. In addition, this function cannot be used with wide character strings.

Alternatively, one of the sprintf functions should be used, as these functions use the setting of the user locale's LC_NUMERIC category when formatting floating-point values. See String Formatting in C and C++ for a discussion on locale-sensitive formatting in internationalized applications.
