US?! — s Exchange y key
In some calculating situations, the roles of x and y may be reversed after
they nave been entered This key can be used to reverse the factors in
multiplication the divisor and dividend in division, or x and y in y»
and *vy
It is also used in statistical calculations and polar to rectangular
conversions, discussed later
