SymPy is entirely written in Python. SymPy is simple to use because it only depends on mpmath, a pure Python library for arbitrary floating-point arithmetic.<\/p>\n<p>Rational and Integer are the numerical types defined by SymPy. A rational number is represented by the Rational class as a pair of two Integers, numerator and denominator, therefore Rational(1, 2) is 1\/2, Rational(3, 2) is 3\/2, and so on. Integer numbers are represented by the Integer class.<\/p>\n<p>SymPy uses mpmath in the background, allowing it to execute arbitrary-precision arithmetic computations.
