Force calculation result as decimal

[vercetty92]

Hi folks,

I come here to ask you a quick question

I am a noob in python and I have a so simple problem. I looked at several python documentations, but I think my poor basic knowlegde of python doesn't permit me to find what I am looking for....so I came here^^

I am not developping a python script, but simply using the calculation feature of ptyhon, which is more powerfull than the one on script shell.
I'm doing it by calling "python -c" from linux CLI

#python -c "print 0.0000006 + 0.0000008"
1.4e-06

question is : how do I force python to have a result in decimal (example 0.xxxxxxxxxx)

Thanks a lot in advance
