numbers that cannot be represented as a ratio of two integers (Mathematics)
number that cannot be expressed as the ratio of two whole numbers (Mathematics)
In
mathematics, an irrational number is any
real number that is not a
rational number — that is, it is a number which cannot be expressed as a fraction m/n, where m and n are
integers, with n non-zero. Informally, this means numbers that cannot be represented as simple fractions. It can be deduced that they also cannot be represented as terminating or repeating decimals, but the idea is more profound than that. While it may seem strange at first hearing,
almost all real numbers are irrational, in a sense which is defined more precisely below.
