A proper fraction is a rational number whose absolute value is less than $1$, expressed in the form $r = \dfrac p q$, where $p$ and $q$ are integers.

Examples

 * $\dfrac 1 2$ is a proper fraction.


 * $\dfrac {-3} 4$ is a proper fraction.


 * $\dfrac 6 {10}$ is a proper fraction, although not in canonical form.
