Hi, doganadres at gmail.com
why don't you use
print("{0:10.5f}".format(x))
The only thing you want is a specific form of the human readable
representation of the number. For this it is not necessary the convert
the *number* itself definitely to a string. You only have to make a
temp copy of x for printing purposes.
Linux Mint Tara in Spyder(Python 3.6) :
x=4.999999999999449e-05
print(x)
4.999999999999449e-05
print("{0:8.5f}".format(x))
0.00005
print(x)
4.999999999999449e-05
