There is a global DecimalSeparator variable available. Please read the VCL
documentation for more details.

But why would you want to change it?

I think that DecimalSeparator defines how the
decimal separator on NUM keyboard behaves...

No, DecimalSeparator defines how decimal values are written and parsed.

DecimalSeparator = ',';
AnsiString Str = 2.5;

Now Str will be "2,5". DecimalSeparator only affects the VCL and not
Standard Library and other libraries.

The ISO C Standard has a function setlocale() ("inherited" in C++ as
std::setlocale()) that you can use to customize the way the C part of
the Standard Library deals with various things, including number
formatting.

In the Standard C++ Library, there is the locale facet std::numpunct
that you can use to customize how streams deal with number
punctuation.
