I have a float variable that is very long.float_a = 1.16667However, I want to pass the value of float_a to float_b, but I want the float to be accurate to two decimal points.float_a = 1.16667 print "%.2f" % float_a1.17 I tried the following:float_b = "%.2f" % float_a float_b'1.17'type(float_b)<type 'str'> This doesn't work because it yields a string. Any suggestions?
If you want control over the precision I'd use the decimal module.
>>> x
1.1666666699999999
>>> y = decimal.Decimal("%.2f" % x)
>>> y
Decimal('1.17')
>>>
