What i meant was they aint whole numbers .....
An irrational number is a number that cannot be expressed as p/q (a fraction) for any integers p and q. Irrational numbers have decimal expansions that neither terminate nor become periodic.
Imaginary numbers = complex numbers = definition already explained
Btw ... i knew the definition of irrational numbers but i was too lazy to type it so
got it here

(this whole thread could be as small as a post or 3 when things were explained correctly and detailed in the first place)
Sorry

i = sqr (-1) .....
Thats what i learnt last year and i am sure it is correct
Sqr of a -ve no is an imaginary number and its combination with a real number is a complex number
EDIT 2:-
Ok here is that sqr(-1) i was saying ....
