# This cop identifies Float literals which are, like, really really really
# really really really really really big. Too big. No-one needs Floats
# that big. If you need a float that big, something is wrong with you.
#
# @example
#
# # bad
#
# float = 3.0e400
#
# @example
#
# # good
#
# float = 42.9
