#  What is this code 'meant' to do?
#  What does this code 'actually' do?
#
#
# TO RUN:  python float2.py
#
# NOTE:  in python floats are actually  C  doubles !
#


print

##
# This is the same as the C and Java versions
# - but as noted Python uses doubles
x = 123456789.0
print x, "+ 1 =", x+1


print

##
# ... so we can get the same effect by using more digits
# this requires us to format the value so it uses fixed notation
# rather than scientific notation
x = 1234567890123456789.0
print '{:f}'.format(x), "+ 1 =", '{:f}'.format(x+1)

# By the way - I've just calculated that I live
distance = 1.2345678901234567
# kilometres from here
#
# Why might you be tempted to question that?
#
# (the solution to that question is a totally different topic!)
