Class IntegerValue

public class IntegerValue extends Value

IntegerValue.

integer_value ::= c-int integer_literal:string

character_value ::= c-char byte

size_value
	::= c-size type
	::= NOSIZE

attribute_address	::= c-aaddr attribute:tag


An integer literal is a string:

	< <radix> R>? <sign>? <digit>+

where digit is one of the (ISO coded) decimal digits, and sign may be + or -. The letter R, if included,
signals that the integer is specified with a radix preceding R. The only legal radices are 2, 4, 8 and 16.
If the radix is 16, <digit> may also be one of the (ISO-coded) letters A-F, with the obvious meaning.

Note that an integer literal may not contain spaces.
