public class Scaled
extends AbstractAssignment

This class provides an implementation for the primitive \scaled.

The Primitive \scaled

The primitive \scaled can be used to define a control sequence as alias for a scaled register. The control sequence can be used wherever a scaled is expected afterwards.

The primitive \scaled is an assignment. Thus the settings of \afterassignment and \globaldefs are applied.

The prefix \global can be used to make the assignment to the new control sequence global instead of the group-local assignment which is the default.

Syntax

The formal description of this primitive is the following:
    ⟨scaled⟩
      → ⟨optional prefix⟩ \scaled ⟨control sequence⟩ ⟨equals⟩ ...

    ⟨optional prefix⟩
      →
       |  \global ⟨optional prefix⟩  

Examples

    \scaled\abc=45  
    \scaled\abc 33  
    \scaled\abc=-1.2

Method Detail

assign

public void assign(Flags prefix,
                   Context context,
                   TokenSource source,
                   Typesetter typesetter)
            throws InterpreterException
Description copied from class: AbstractAssignment
The method assign is the core of the functionality of execute(). This method is preferable to execute() since the execute() method provided in this class takes care of \afterassignment and \globaldefs as well.

Specified by:
assign in class AbstractAssignment
Parameters:
prefix - the prefix controlling the execution
context - the interpreter context
source - the token source
typesetter - the typesetter
Throws:
InterpreterException - in case of an error
