Decimals in python

[arslanburney@gmail.com]

Hello. New to using Python. Python automatically round off watver i
calculate using the floor function. How wud i make the exact value
appear?

Tried out fabs() in the math library but still confused. Cud some1
elaborate on it.

If you're working with integers, the result will always be an integer:

>>a = 10/3
>>print a

3

How ever if you add a float into the mix:

>>a = 10/3.0
>>print a

3.3333333333333 335

[python]
---help(math.floor ):
Help on built-in function floor in module math:

floor(...)
floor(x)

Return the floor of x as a float.
This is the largest integral value <= x.
[/python]

The whole point of floor() is to round down. If you want to see all the
decimals, don't use floor(), and follow Aidan's advice to have at least
one floating-point number in the calculation.
