Some numbers such as pi, e, and square roots are used quite commonly. Whether you use them at all will depend on what you do in your everyday life, of course. Engineers might use them commonly; others not so much.Even for an engineer, or ESPECIALLY for an engineer, the distinction between rational and irrational is irrelevant for most practical purposes; for instance, if you round pi, or the square root of 2 (which are both IRRATIONAL), to 10 or 15 significant digits, you get a RATIONAL number - and the resulting precision is more than enough for most purposes. (In fact, if you round to ANY number of digits, the result will still be rational.)

The diagonal of a square with unit sides is an irrational number. pi, which is a key constant in geometry and calculus, is irrational. Euler's number, e, which is a fundamental constant in slightly more advanced calculus is irrational. Irrational Numbers appear all over the in everyday life.
