Converting floating point to string in non-scientific format

[Madhusudhanan Chandrasekaran]

Hi all:

When I try to convert a float variable into string via repr() or str()
function, i get the value as is, i.e '0.1e-7' in IEEE 754 format.
Instead how can force the created string to represent the floating
point in non-scientific fashion (non IEEE 754 format)? i.e
something like 0.000000001

Thanks in advance for your help.

Use the % operator with the f format (e.g., '%.7f' % x).
