Print a float number in normal form, not exponential form / scientific notation

Question

I have a number that prints out in exponential form:

>>>
>>> a = 1/1221759
>>> print(a)
8.184920266599223e-07
>>>

How can i make it print in normal form?

You can format it as a fixed-point number.

>>> a = 1/1221759
>>> '{0:.10f}'.format(a)
'0.0000008185'

returns '0.0000000000' for me? – niken Jun 10 '16 at 15:21

@Nik because Python 2.7 returns int with `/` operator. Py3 returns float. Put a decimal point at the end of `1221759` – Peter Badida Jun 25 '16 at 10:49

You can use print formatting:

print "%.16f" % a

where 16 is the number of digits you want after the decimal point.
