Float problem

It is just me thinking strangely again, or am I correct in assuming the
fact that my D6 image evaluates

        Float fmin > 0

and returns true, is not quite correct?

Cheers

Is it is correct
Float fmin = 2.2250738585072e-308

Remember:
(intBase raisedTo: intExp negated) = (1 / (intBase raisedTo: intExp))

Evaluate this in Dolphin:
(27 raisedTo: -3) = (1 / (27 raisedTo: 3))

A positive number raised to a negative number is always > 0. (1/xxxxxx)

It's 2^(-308) or so, which is a very(!!) small positive number, so the
test is correct.

Have a good one,
