Display a float with two decimal places in Python.

Floating-Point Types. Almost all platforms map Python floats to IEEE 754 double precision. a = Decimal(.0.1.) b = Decimal(.0.2.) c = a + b # returns a Decimal representing exactly print "%.2f" % 1.2399 # just use print and string formatting. "string format" is by far the most flexible and Pythonic approach. So far we have used Our float number 59.058 has to be formatted with 8 characters. g, Same as "e" if exponent is greater than -4 or less than precision, "f" otherwise. G, Same.
