# Integer to English

Here is my try of changing integers to English written numbers.

Here corrected version 3 check:

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())``

Example output:

Sorry for the "dirty code".

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

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'
