Hello!
(Reading time: 45 seconds)

I made the program below, to calculate a log of a number in a given basis.

≪CLEAR
"LOGa(b)
Enter a b"
"" INPUT OBJ→ → A B
≪ 'LN(B)/LN(A)' EVAL
"log" A "(" B ")" + + + + →TAG
≫
≫

Lets calculate
log2(500)

Result:
log2.(500.):8.96578......

I need press

to see:
log2.(500.):8.96578428466.
that is the full number.

My questions are,
1 - How can I from inside a program made the same as
press ?

2- How can I remove dots after the numbers link 2. and 500. in log2.(500.)?
