问题描述





i有关于VB String的双重转换以及C ++ CString转换为双倍的问题。



i在VB中有一个值:



String - > 2.48365014976068



在VB中他们使用Val函数转换为double时他们在double中得到相同的值,即(2.48365014976068)




$ C $ b in C ++:



String - > 2.48365014976068


$ C $ b在C ++中从CString转换为double的两倍是(即2.4836501497606802)



vb和c ++给出不同的值..请帮助我



我尝试过的事情:



VB:

double d = Val(2.48365014976068)



C ++:

double d = _tsof(2.48365014976068)

Hi,

i had got issue regarding VB String to double conversion and C++ CString to double conversion.

i have a value in VB :

String -> 2.48365014976068

in VB they are using Val function while converting to double they are getting the same value in double as well i.e (2.48365014976068)


in C++:

String -> 2.48365014976068

in C++ while converting from CString to double the value in double is ( i.e 2.4836501497606802)

both vb and c++ giving different values ..please help me

What I have tried:

VB:
double d = Val(2.48365014976068)

C++:
double d = _tsof(2.48365014976068)
