An irrational number is any real number that cannot be expressed as a ratio a/b, where a and b are integers, with b non-zero, and is therefore not a rational number. An integer is any real whole number. Basically, this means that an irrational number cannot be represented as a simple fraction.
This involves type of numbers.
Their differences are explained below.
- Generally, numbers are classified as either Real numbers or Complex Numbers.
- Real Numbers have two major groups namely Rational Numbers and Irrational Numbers.
Now, Rational numbers include integers, whole numbers, fractions, finite decimals e.t.c.
- An integer is defined as any whole number that can be positive, negative or zero. Examples include; -1, -2, -5, 0, 1, 2, 5, 9 e.t.c. Whole numbers means they cannot be fractions nor decimals.
- An irrational number is defined as any real number that cannot be expressed as a ratio of two integers. This means they cannot be written as simple fractions and when they are written as decimals, the decimals are usually terminating and non-repeating.
