Or if you need the greater range in the exponent.  Or if you don't want 
to get tripped up by errors that accumulate when the data is constantly 
being changed back and forth between float and double as you use math 
functions. Or if you don't like being taken by surprise by unexpected
behavior because you forgot that the compiler presumes that non-integral
constants are doubles unless you tell it otherwise.  Or . . .

Intel Schmintel.  Because of how C and C++ and their standard libraries
have evolved, a programmer should by default use doubles rather than
floats unless both she knows what she's doing and she has a compelling
reason to do so.
