10.10.10.5 Term Expressions

A term expression has one of the following forms, where T1 and T2 denote term expressions, X denotes a variable, I denotes an integer, and S denotes the current store.

min(X)

evaluates to the minimum of D(X,S)

max(X)

evaluates to the maximum of D(X,S)

card(X)

evaluates to the size of D(X,S)

X

evaluates to the integer value of X. The indexical will suspend until X is assigned.

I

an integer

inf

minus infinity

sup

plus infinity

-T1

evaluates to S(T1) negated

T1+T2

evaluates to the sum of S(T1) and S(T2)

T1-T2

evaluates to the difference of S(T1) and S(T2)

T1*T2

evaluates to the product of S(T1) and S(T2), where S(T2) must not be negative

T1/>T2

evaluates to the floored quotient of S(T1) and S(T2), where S(T2) must be positive

T1/<T2

evaluates to the ceilinged quotient of S(T1) and S(T2), where S(T2) must be positive

T1 mod T2

evaluates to the floored remainder of S(T1) and S(T2)

T1 rem T2

evaluates to the truncated remainder of S(T1) and S(T2)
