# CLP(R)

CLP(R) is a declarative programming language. It stands for Constraint logic programming (Real) where real refers to the real numbers. It can be considered and is generally implemented as a superset or add-on package for a Prolog implementation.

## Example Rule

${\displaystyle {\begin{cases}3x+4y-2z=8\\x-5y+z=10\\2x+3y-z=20\end{cases}}}$

are expressed in CLP(R) as:

3*X + 4*Y - 2*Z = 8,
X - 5*Y + Z = 10,
2*X + 3*Y -Z = 20.


and a typical implementation's response would be:

Z = 35.75
Y = 8.25
X = 15.5

Yes
