[issue26223] decimal.to_eng_string() does not implement engineering notation in all cases.

[Antti Haapala]

Antti Haapala added the comment:

Ok, after reading the "spec" it seems that the engineering exponent is indeed printed for positive exponents *if* the precision of the number is less than the digits of the exponent, which I didn't realize that I should be testing. 

However the *precision* of decimals is meaningless anyhow. Add a very precisely measured '0e0' to any number and the sum also has exponent of 0, and is thus never displayed in exponential notation.
