Hi there,
I am using python to do some scripting. In particular, I am using it
to run some jobs which require precision inputs. I do this by having
python write an input file, which I then feed to some other program.
The problem I am having is getting python to write number into this
input file, keeping 16 digits of precision. I have played around
interactively, and see that python default prints 17 digits of
precision to the screen, but when I use a replace command to write
into the input file, it only prints 12 digits of precision. The
relevant snipit of my script is
value = float( int(ai) * 6 * math.pi / (int(L)*int(T))
replace = {'VALUE':str(value)}
ini_file = open('generic_ini').read()
f=open('my_input.xml','w')
f.write(ini_file % replace)
f.close()
where, "ai", "L" and "T" are process dependent numbers defined in my
script, and the output "my_input.xml", is just an xml file I later
feed to another program, and this is why I replace 'VALUE' with a
string.
To reiterate, I need str(value) to be written to my file with 16
digits of precision...???
Thanks,
Andre
