No, but I never learned to use one well, even through calculus. I've always done my math leaving in the fractions/radicals/irrational numbers, so being confined to decimal output messes with me. I find I'm never sure if it's right. If someone needs a decimal answer from me, I can always just use a software app to convert my final answer to a decimal.
I don't have to do a lot of math in my daily life, but I'm more proficient working with fractions and doing arithmetic in my head than I am doing it on a calculator.
