Integer color sets

Integers are numerals without a decimal point. The integer color set is large unless restricted by the with clause, in which case it is small.

Declaration syntax

colset name = int [with int-exp1int-exp2];

Order

usual ordering of integers

Optional ''with'' clause

Restricts the integer color set to an interval determined by the two expressions in int-exp1 and int-exp2. It must be the case that int-exp1<=int-exp2.

Declaration examples

colset INT = int;

colset SmallInt = int with 1..10;

An integer color set using the with clause is used in the example CP-net Simple protocol example.

var smallInt : SmallInt;

The CPN variable smallInt may have a range of integer values from 1 to 10. For example, 2 is a legal value, but 11 is not and 2.9 is not.

Operations

~i
negation of the integer value i
i1 + i2

i1 mod i2
modulus, remainder
abs i

Int.min(i1,i2)
minimum of i1 and i2
Int.max(i1,i2)
