一个格式化数字字符串函数

又是剽窃核心编程

// This function accepts a number and converts it to a // string, inserting commas where appropriate. PTSTR BigNumToString(LONG lNum, PTSTR szBuf, DWORD chBufSize) { TCHAR szNum[100]; wsprintf(szNum, TEXT(“%d”), lNum); NUMBERFMT nf; nf.NumDigits = 0; nf.LeadingZero = FALSE; nf.Grouping = 3; nf.lpDecimalSep = TEXT(“.”); nf.lpThousandSep = TEXT(“,”); nf.NegativeOrder = 0; GetNumberFormat(LOCALE_USER_DEFAULT, 0, szNum, &nf, szBuf, chBufSize); return(szBuf); }
