Question

MFC编程中CString转float问题！

需要将一个CString转换成float，比如说35689转成356.89，然后与另个float进行计算得到结果之后再转换成CString，比如258.75转成25875！谢谢了

Answer 1

字符串转float

atof(char * pszFloat);

float 转字符串：

sprintf(pszStr,"%f",fVar);

#include <stdio.h>
#include "afx.h"
void main()
{
float fVar;
CString str="1.23",resu;
fVar=(float)atof(str);
fVar*=2;
sprintf((LPSTR)(LPCTSTR)resu,"%f",fVar);
printf("%s",resu);
}

请点击选为满意答案，谢谢

Answer 2

cstring a = "35689";
float fa = atof(a);
fa *= 0.1;
float fb= 100;
float fc = fa * fab;
csting sc = "";
sc.Format("%f",fc);

Answer 3

CString a = "35689";
float f;
sscanf(a, "%f", &f);
f /= 100;

这样行吗
需要 stdio.h
