The ACOS function

G

Guest

Does MS Access provides the ACOS function (also called arccosine), where it
returns the angle, in radians, whose cosine is the given float expression? If
not, how can I create one?

Look in the VB help for "Derived math functions". In there it claims
that...

Arccos(X) = Atn(-X / Sqr(-X * X + 1)) + 2 * Atn(1)
