In Julia, there is the `isapprox` function to inexactly compare 2 numbers. (you can use it in infix form: `x≈y`. By default, two numbers are approximately equal if their relative tolerance is less than `sprt(eps(typeof(x))` (around 1e-8 for 64bit Floating point numbers)

Using equality to compare 2 floating point numbers doesn't get you anywhere, specially if you are using mathematical functions (the implementation of `sin` or `exp` could vary with operating systems or software versions)
