declaimed the following in gmane.comp.python.general:
how much is one half times one half?
import math
print math.exp((math.log(1) - math.log(2))
+ (math.log(1) - math.log(2)))
That's all well and good, but base 'e' is kind of complicated. Some
of us were using base 10, and others took Tim's lead and were using
base 2:
>>> print math.exp(((math.log(1)/math.log(2) - math.log(2)/math.log(2)) +
(math.log(1)/math.log(2) - math.log(2)/math.log(2)))*math.log(2))
0.25
The above can be rewritten as
print('0.25')
which is much faster and also a lot more readable.
