Problem with float values printing

[matekm]

I have program that prints float values (I need this for testing). And
it works almost fine. The thing is that when I want to print 1e-01
(for example) it prints 1e-01 on Linux (g++) and 1e-001 on Windows
(Visual Studio 2008, default empty solution). Is there any way to
standarise this? I would like that on Win and on Lin std::cout print
1e-01.

Thanks for help!

*I* think there is a defect in VS2008 (that has existed since who knows
when) that causes it to print three zeros when only two should be
printed (C Standard, description of 'fprintf', 'f,F' conversion
specifier. Try asking about it in 'microsoft.public.vc.language'.

If you want to make sure you always have the right number of digits, try
forming the string yourself (yes, it's tedious).

Ok, there is a way to do it.

_set_output_format(_TWO_DIGIT_EXPONENT);

Wow... I learn something new every day!
