ansistring 转 char 代码:
char转ansistring 代码: 【程序编程相关:迷茫？ping广播地址的回应】
void __fastcall tform1::button1click(tobject *sender) { ansistring test = "哈哈"; char *chr = test.c_str(); } 【推荐阅读:网站配色奥秘大公开】
ansistring转int 代码: 【扩展信息:WebService Notes】
#include <windef.h> void __fastcall tform1::button1click(tobject *sender) { ansistring str = "sample"; char chr[max_path]; strcpy( chr , str.c_str() ); }
void __fastcall tform1::button1click(tobject *sender) { ansistring test = "123"; int i = strtoint( test ); }
int转ansistring 代码:
void __fastcall tform1::button1click(tobject *sender) { int i = 123; ansistring str = inttostr( i ); }
ansisting转double 代码:
void __fastcall tform1::button1click(tobject *sender) { ansistring test = "123"; long double d = strtofloat( test ); }
double转ansistring 代码:
void __fastcall tform1::button1click(tobject *sender) { double d = 123.456; ansistring str = floattostr( d ); }
double转ansistring并四舍五入
代码:
void __fastcall tform1::button1click(tobject *sender) { long double d = 123.456121212; ansistring str = floattostrf( d , fffixed ,5 , 4 ); //说明floattostrf里5代表从第几个数字的后一位开始四舍五入,4代表取4位小数.... 下一页
