I have a real number....
float r
and I want to store it into
char floatstr[6]
How do I get to do it?

Or: Do you know how I can display a real number using DrawText, TextOut, SetDlgItemText.... etc?

Please reply soon!

I would use double instead of float.


Use: double  d;
     TCHAR   str [ 32 ];

     _stprintf ( str, "%.2f", d );

Or check into the ecvt, fcvt, gcvt function in stdlib.h

Don't worry, be Kneppie!

below a way to make a string with a double

char* str_double(char* s, const double d, const int prec, const char mod) {
//prec=nb chiffres apres le . decimal, 0 -> 6
//mod='f,'e/E','g/G'
//f -> format decimal: [-]dd.dddd
//e/E -> format scientifique: [-]d.dddd e/E+-dd
//g/G -> f si precision suffisante, e/E sinon
//return s
 char format[16];
 strcpy(format,"%-.");
 format[3]=(prec==0) ? '6' : '0'+prec;
 format[4]=mod;
 format[5]=0;
 sprintf(s,format,d);
 return s;
}
