I changed logarithm function to be log1000 instead of log 10 to get rid of dividing by 3 by putting while test to test <1 instead of <10, therefore giving one too big number, which I fixed where I used it at line 26. Proper fix of lines 17 until 26 is:

def log1000(n):
    " integer log10 "
    res=0
    while n>1000:
        res+=1
        n/=1000.0
    return res

def inttoeng(number):
    unit=log1000(number)

ie test <1000 and remove the -1 from line 26. (the doc string I fixed in my resend of the code in main message.

To get some more variation of the test numbers use this random number instead (it produce logarithmic random numbers):

num = int(random.randint(0,10**random.randint(5,50))*random.random())

Sorry for the "dirty code".

Edited 6 Years Ago by pyTony: n/a

Bug fixes: would not print 'zero', equality missing from log1000 (therefore ten hundred)

Negative numbers added.

Explain function is useful help function, even very simple.

QUIZ: what number are these relative numbers?

'one million forty-eight thousand five hundred and seventy-six'

'eighteen quintillion four hundred and forty-six quadrillion seven hundred and forty-four trillion seventy-three billion seven hundred and nine million five hundred and fifty-one thousand six hundred and sixteen'
