gcvt − convert a floating-point number to a string
#include <stdlib.h>
char *gcvt(double number, size_t ndigit, char *buf);
The gcvt() function converts number to a minimal length NULL terminated ASCII string and stores the result in buf. It produces ndigit significant digits in either printf(3) F format or E format.
This function is obsolete. Instead, sprintf() is recommended.
The gcvt() function returns the address of the string pointed to by buf.
