ansistring 转 char
代码: 【相关文章:何为博客？】 【扩展阅读:微软在北大软院所开设课程的内容记录,敬请】 【扩展信息:C++的对象互斥访问】void __fastcall tform1::button1click(tobject *sender)
{ ansistring test = "哈哈"; char *chr = test.c_str(); } char转ansistring 代码:#include <windef.h>
void __fastcall tform1::button1click(tobject *sender) { ansistring str = "sample"; char chr[max_path]; strcpy( chr , str.c_str() ); } ansistring转int 代码: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。 //执行后得到str是123.4600。:roll: }
double转ansistring使用类似vb的format函数
