Math Constants - are lots of decimal places OK?

I want to slightly increase the number of decimal digits to cover any
conceivable
future expansion.

It would help me to know if anyone has trouble compiling the following
with current compilers (because it has too many decimal digits).
(I have had a report of failure by some compiler(s) in the past,
but I think it/they may be cured now.

Perhaps you can slip it into some code you are working on,
and delete if compiles OK.

{ /* Test a silly number of decimal digits */
#define BOOST_SQRT2 1.4142135623730950488016887242096980785696718753769L

const long double sqrt_2 = (long double) BOOST_SQRT2;

#undef  BOOST_SQRT2
}

Thanks

Paul
