I guess it is never coming out of your while loop. Have a look at the
Rails Guide on debugging to find out how to break into code using
ruby_debug and see what is going on. Also you could try putting some
write statements in the function to see what is happening.

Hint: It may not help but what happens if you try squareroot(55.0)?
If that helps make sure you understand why (using debug or print
statements).

puts "Hello World"
def squareroot(a)
   u=a
   l=0
   while (l<=u)
     m = l + (u-1)/2

        puts "u = #{u}, l = #{l}, m = #{m}"

     if (m**2) < a

[snip rest of code]

Try adding in that extra line of code and I think you might understand your logic error.
