erm dunno whats happening right now, try to make a square root calculator. I feel really stupid, feel like im doing everything wrong.... lol havnt programmed in a while

Am I doing it completely wrong?

input "enter a number to find the square root",z
squareroot(z)
cls
print t
end

function squareroot(z)
do
b = b + 1
b*b=t
if t = z then exit
loop
endfunction

that won't even compile, and even if it did the function would only ever exit in the case of a perfect square. You cant assign 't' to b*b, you have to flip the sides around.

@ sirsiddy

The code you posted only works if the square root is a perfect square (i.e. 9=3 81=9, etc.) If you enter 112, for example, it just locks up.

Heartbone's code works fine and is shorter and cleaner. You should just use that.
