 DPL ( -- addr )

 DPL is a variable. The cell at addr describes the location of last
 punctuation mark in the number most recently converted by the system.
 (The word >NUMBER does not affect DPL, but more high-level number
 conversion words do.) If the value at addr is negative, the number
 was unpunctuated. If it is non-negative, it represents the number
 of digits to the right of the last (rightmost) punctuation character.

acceptance:
 wide; DPL is mentioned in Forth-83 as a uncontrolled reference word
 ../../standard/fst83/fst83-b.htm#d-p-l
 and may be found in many systems.

note:
 This definition explains why in Forth numbers with the decimal point
 are double numbers: the decimal point is reserved for use in
 fixed-point math packages; DPL is also meant to be used there.
