Question

Like the question says. Converting to / from the (truncated) string representations can affect their precision. But storing them in other formats like pickle makes them unreadable (yes, I want this too).

How can I store floating point numbers in text without losing precision?

Answer 1

I’d suggest using the builtin function repr(). From the documentation:

repr(object) -> string

Return the canonical string representation of the object.
For most object types, eval(repr(object)) == object.
