i've got a function that does exactly that. i already posted it before, so
if you would have searched a bit you would have found the code to do that...
(STFW)
void NumFormat(Char *strP, double dvalue, short dec){
Char *buf = MemPtrNew(50);
Char *szDec = MemPtrNew(20);
Int32 lpow = pow(10, dec);
Int32 i = (Int32)dvalue;
Int32 d = (dvalue - i) * lpow;
// round the last decimal!
UInt8 tmp = (dvalue*lpow*10) - (i*lpow*10);
if(tmp > 4) d++;
StrIToA(buf, i);
if(dec){
if(d < 0) d *= -1;
StrIToA(szDec, d);
StrCat(buf, ",");
for(i = 0; StrLen(szDec) + i < dec; i++) StrCat(buf, "0");
StrCat(buf, szDec);
}
StrCopy(strP, buf);
MemPtrFree(buf);
MemPtrFree(szDec);
}
