Enter a rational number with very big integers in the numerator and denominator: Rational numbers are represented with the smallest possible positive denominator: The FullForm of a rational number is Rational [ numerator , denominator ] : A rational number is a number that can be in the form p/q. where p and q are integers and q is not equal to zero. So, a rational number can be: p q. where q is not zero.

type of number are the rational numbers (often simply called the rationals), which are all of the possible òratios ó (i.e. quotients) of integers. This set of numbers is usually represented2 by the symbol ℚ. As we have seen firsthand, there are numbers with real, physical significance that are not rational.

Usage The ℚ symbols is used in math to represent the set of r The real number system is by no means the only field. The {} (which are the real numbers that can be written as r = p / q, where p and q are integers and q ≠ 0) also form a field under addition and multiplication. The simplest possible field consists of two elements, which we denote by 0 and 1, with addition defined by 0 + 0 = 1 + 1 = 0, 1 ...The relational operators are often used to create a test expression that controls program flow.

The real number system is by no means the only Irrational Number Symbol. Generally, the symbol used to represent the irrational symbol is “P”. Since irrational numbers are defined negatively, the set of real numbers (R) that are not the rational number (Q) is called an irrational number. The symbol P is often used because of the association with the real and rational number.
