A little too much so, I think. There are no invalid casts in Thomas's code.
Converting chars to doubles is just fine, as is converting doubles to long
integers.

You cannot simply typecast between two incompatible types!!! Have you heard
of stol() or stod() or whatevet they're called... Can't remeber now, my
mind is on /^perl$/o at the moment...
