Hi Guys!
I'm trying to compare the numeric value of two objects, one is a vector with only one numeric value and the other is a real number; [1/2]==0.5 the Hp Prime returns a zero.

result:=[1/2]

and do result(1)==0.5 it works on my emulator. You can access a list or vector by round brackets. First element index 1.

rigorously speaking, a vector with only one component is always a vector, non a real...
So, TYPE([½])= 4 (matrix or vector), and type([½]) = DOM_LIST, and in fact is also a list)

You must use [½](1) to get a value 0.5, and then
type([½](1)) = DOM_RAT and TYPE(...) = 0, a real

I hope this could help you.
