MATLAB: Is the code dont stoping when ‘x’ is equal to 10

Question

x=0;
while x ~= 10
    x = x + 0.1
end

Answer 1

You need to know that it‘s because of floating-point error because .1 is not exactly .1 to check

sprintf('%.32f',.1) % you will see numbers after the decimal Point

Search with the tag floating-point in this forum you will find lot of discussions. You need to add tolerance to your while loop:

while abs(x-10)>1e-4

Note: You don‘t need a loop to do this task, it can be vectorised.

x = .1:.1:10
