Encoding tables for constants

A constant is encoded as a series of instructions, where each instruction defines a digit of the constant, from the least significant to the most significant.

Each instruction has a right part defining the digit, and a left part defining its attributes.

Right part of the instruction
S	0
	1
	2
	3
+	4
-	5
	6
:	7
	8
*	9

Left part of the instruction
Last digit?	Sign	Decimal point	Code
Yes	+	Yes	D/
		No	D
	-	Yes	E/
		No	E
No	+	Yes	R/
		No	R
	-	Yes	F/
		No	F

Examples of encoded constants:

250.34 must be encoded as:

A  /		Marks the start of an encoded constant
R +	4	+ says it's a four R says it's not the last digit, it's a positive number, and it doesn't have the decimal point
R	3	says it's a three R says it's not the last digit, it's a positive number, and it doesn't have the decimal point
R / S	0.	S says it's a zero R / says it's not the last digit, it's a positive number, and has the decimal point (i.e., this is the digit that expresses units)
R  -	5	- says it's a five R says it's not the last digit, it's a positive number, and it doesn't have the decimal point
D	2	says it's a two D says it is the last digit, it's a positive number, and it doesn't have the decimal point

-10 must be encoded as:

A  /		Marks the start of an encoded constant
F / S	0.	S says it's a zero F / says it's not the last digit, it's a negative number, and has the decimal point (i.e., this is the digit that expresses units)
E  -	1	- says it's a one E says it is the last digit, it's a negative number, and it doesn't have the decimal point

1 must be encoded as:

A  /		Marks the start of an encoded constant
D /	1.	says it's a one D / says it is the last digit, it's a positive number, and has the decimal point (i.e., this is the digit that expresses units)
