The numbers are, of course, stored in binary so the real question is: can we *display* them in scientific format? The answer is yes using string format operators. Try playing with the %e and %g options: >>> val = 123456789453286432976.5309764 >>> print "%e" % val >>> print "%g" % val >>> print "%E" % val >>> print "%G" % val You can also control how many decimal places are displayed too >>> print "%.4" % val And the total number of digits, and the justification. Well worth browsing the documentation on string formatting. There are also ways of getting engineering notation (ie the powers are multiples of 3, but I've forgotten for now how that's done!)
