Attach Unit function.

Attaches a number to a unit name. Intended to be used for the creation of unit objects, such as  (two inches).

Note: The  (underline) function acts like (multiplication) if the input is two real numbers, or a name and a number. If the second argument is a name or an algebraic, it is ’d and turned into a unit (if possible) before the multiplication is performed. Examples:

    

    
HP49/50 oddity (in exact mode only!):
      (a real, same as HP48)
      (an integer! strange.)

HP48:        
HP49/50:     
Pressing the key turns on algebraic mode. To turn it back off, either press the ENTRY key (RS-ALPHA) or perform any operation that is not allowed inside an algebraic expression.
