I create 2 edit box, say inter and result
If I type any number then I want result in edit box
(1) Prime number
(2) any number in P/Q terms (rational number) i.e. 0.3333....(inter) = 1/3 (result), 0.5 = 1/2 etc
and 24/28 = 6/7
(3) sqr 8 (inter) = 2*sqr2 (result
(4) Factorial 3! (inter) =6 (result), 4! = 24 etc
How ?????
