public class NumberedReal
extends NamedReal

This class provides an implementation for the primitive \real. It sets the named real register to the value given, and as a side effect all prefixes are zeroed.

All features are inherited from Real. Just the key has to be provided under which this Real has to be stored. This key is constructed from the name, a hash mark and the running number.

Example

 \real12=345.67
