To Zaxo & Halley
Actually, I already knew all that 0 vs 0.0, true vs false stuff. :-)
My query was that given $cost starts as a float and then sometimes has an integer added to it, why is the result integer, not float? I'm sure that in the background int is promoted to float for the actual calc, and given the tgt is already a float, I'd expect a float result?
Surely that's a reduction of the variable?
As implied above, this code I inherited(!) doesn't print the value, it's just used for a boolean test.
Cheers
Chris
I'm just trying to understand the internals a bit more.
