long-string number in Visual C++

[thornybird80]

Hi, I am working on a project using visual C++. I encounter a problem: when i input a number with a very long string, say 3.444444444444444444444444444444444..., the VC-based program will automatically close without even an error message. Could anyone here give me some hints regarding how to deal with the issue? Thanks.

Need far more info than you have presented. How are you entering this string into what type of variable from what form or is it a console app? Are you converting from a string to a number or is it a number field that you are entering the data into? Please post at least a code snippet to give us more info.

Do you want to round it ? If you want to preserve the accuracy to so many digits you have to write your own
arithmetic library -- and you can't use the co-processor
-- at least not so easily
