Hi,
I am having trouble with an expression.
I have the following line of code:
self.failUnless(c.as == 65215)
What happens when you compile this is that you get a syntax error.
This is because as has been made a keyword. failUnless is from the
module unittest.
Now my problem is this. the ".as"

I want the mantissa and decimal exponent of a float, in base 10:
mantissa and exponent of 1.2345e7
=> (1.2345, 7)
(0.12345, 8) would also be acceptable.
The math module has a frexp() function, but it produces a base-2 exponent:
