In mathematicsan irrational number is any real number which cannot be expressed as afraction p/q, where p and q are integers, with q non-zero and istherefore not a rational number. Informally, this means that anirrational number cannot be represented as a simple fraction. It can beproven that irrational numbers are precisely those real numbers thatcannot be represented as terminating or repeating decimals, althoughmathematicians do not take that to be the definition. As a consequenceof Cantor's proof that the real numbers are uncountable (and therationals countable) it follows that almost all real numbers areirrational. Perhaps the best-known irrational numbers are ¿, e and ¿2.When the ratio of lengths of two line segments is irrational, the linesegments are also described as being incommensurable, meaning they shareno measure in common. A measure of a line segment I in this sense is aline segment J that 'measures' I in the sense that some whole number ofcopies of J laid end-to-end occupy the same length as I.…
