Java Calculator program issue

I am trying to develop a calculator program that inputs an arithmetic expression of the form number operator number = and computes the result of the expression. The expression will be evaluated from left to right not considering regular operator precedence. For example, the expression 14 – 5 * 3 = will produce 27.0. The value = displays the final

Comparison of Double Constants

I researched this a lot and I know something about precision errors in the doubles; however I couldnt find the answer. My question is: is it always safe to compare double constants? What do I mean by that is, just reading the double from a string or creating in the source code. No operation (adding, subtracting etc.) will be done

How can I intentionally create random floating point / decimal precision errors in java?

My goal is to generate random numbers that all have decimal precision errors. Here are some examples of types of numbers I would like to generate: Here are strategies I have tried. parseFloat(“4.01500000000000000001”); BigDecimal.valueOf(ThreadLocalRandom.current().nextFloat()).multiply(BigDecimal.valueOf(ThreadLocalRandom.current().nextFloat())).doubleValue(); None of the things I tried have created even a single number similar to that which I am looking for.
