When I have a while loop that goes as long as x does not equal 1.0, then it does the operation x = x + .1. The result is an infinite while loop. Why does this happen
Never test for exact equality using reals! Always do a comparison along the lines of |x - 1|<10^-6 .
Its better to have a worksheet to see what you actually did.
Maybe you ran into a accuracy problem. Not sure though.
Maybe not : "while x does not equal 1"
but rather: " while x is less than 1"
