Description copied from interface: CountConvertible
This method converts a register into a count. It might be necessary to read further tokens to determine which value to use. For instance an additional register number might be required. In this case the additional arguments Context and TokenSource can be used.

Parameters:
context - the interpreter context
source - the source for new tokens
typesetter - the typesetter to use for conversion
Returns:
the converted value
Throws:
InterpreterException - in case of an error
