Please help! 10**32 ~ Final result is 99999999Y

I cannot get where I have a mistake because in my dle everything works well =( Final result in the test 99999999Y instead of 10000000Y.

def friendly_number(number, base=1000, decimals=0, suffix='',
                powers=['', 'k', 'M', 'G', 'T', 'P', 'E', 'Z', 'Y']):
n = 0
template = '{:.' + str(decimals) + 'f}'
if abs(number) >= base:
  while abs(number) >= base and len(powers) - 2 >= n:
    n += 1
    number = (number / base)
  if decimals == 0:
    number = int(number)
  else:
    number = template.format(number)
  out = str(number) + powers[n] + suffix
else: 
  out = template.format(number) + powers[n] + suffix
return str(out)
