Re: Guideline to save 0 or NULL to a NUMBER column

Ok, I'll take a stab at it....

The assumption is:

e^(pi*i) - 1 = 0

which, adding one to both sides, is equivalent to:

e^(pi*i) = 1

Using ln(e^x)=x and if (a=b), then (ln a=ln b):

pi*i = ln 1

Knowing that ln 1 = 0 (e^0=1):

pi*i = 0

Divide both sides by pi:

i = 0 != sqrt(-1)

A contradiction has been raised. Therefore the assumption is incorrect.

Cheers,
Brian
