# UnsignedRational Structure
 
This class represents unsigned rational numbers.
 
**Namespace:** [Aurigma.GraphicsMill](https://www.graphicsmill.com/docs/gm5/N_Aurigma_GraphicsMill.htm.md)
 **Assembly:** Aurigma.GraphicsMill (in Aurigma.GraphicsMill.dll)

## Remarks
  
Rational number is a number which may be represented as a division of two natural numbers.For example, 3/4, 2/1, 1/6, etc. Not all fractional numbers are rational. For example, a Pi number is *irrational* (i.e. cannot be represented as a division of two natural numbers).
 
This class provides an access to [Dividend](https://www.graphicsmill.com/docs/gm5/P_Aurigma_GraphicsMill_Rational_Dividend.htm.md) and [Divider](https://www.graphicsmill.com/docs/gm5/P_Aurigma_GraphicsMill_Rational_Divider.htm.md). A [Divider](https://www.graphicsmill.com/docs/gm5/P_Aurigma_GraphicsMill_Rational_Divider.htm.md) cannot be zero.
