That's half-true. Most applications IME that manipulate numbers need to
express zero frequently as initializers. So yeah, it's easy to just
write things like::
total = dzero
balance = dzero
but I think there's definitely some utility from writing::
total = 0.0d
balance = 0.0d
How much utility (especially from the readability side) is of course
subject to debate, but please don't ignore it altogether.
