I'd have thought - unless someone corrects me - that they both have the same meaning as they do in basic arithmetic. By a whole number you mean an integer, and by an irrational number you mean a number that can't be represented as the ratio of two integers. 5 and -5 are whole numbers; 4.5 isn't. 14/32 is a rational number; the square root of two and pi are not.
