The Bablyonians did use a place-value system, but they only had two
basic numerals: a Y-like symbol for 1 and a <-like symbol for ten.

Floating point arithmetic is inh
Hey i have a stupid question.
How do i get python to print the result in only three decimal place...
Example>>> round (2.9954254, 3)
2.9951
but i want to get rid of all trailing 0's..how would i do that?

And where does the word 'bit' come from, hmm? It couldn't possibly be an
abbreviation of Binary digIT, could it?

Yes. The interpreter prints back the repr of a, which reflects the
imprecision inherent in floats. If you want '1.1', use the string
returned by the str function.
>>> a = 1.1
>>> a
1.1001
>>> repr(a)
'1.1001'
>>> str(a)
'1.1'

Yes, for floating-point numbers. This is due to inherent imprecision
in how floats are represented in hardware. If you can live with being
a touch off that many decimal plac

It is on Windows, Linux, Python 2.3:

Type "help", "copyright", "credits" or "license" for more information.
