floating point error: overflow?

[C. Sengstock]

Hi,

i´ve got an iteration with random generated floating point numbers.
During the iteration process sometimes the programm stops with the error:
"floating point error: overflow"

Is the number out of range? what does it exactly mean?

Thanks, Chris

Essentially yes.

You tried to store a representation that is
invalid for a floating point type on your
implementation.

Not even store, necessarily. Just generate.

double d = DBL_MAX;
++d;

....can generate an exception or trap.

BTW, could you start using a proper signature separator?

Right. Thanks.
double d = DBL_MAX;
++d;

Sure, as soon as I start using a sig.
