• S : Type

This domain is used to interface with the interpreter's notion of comma-delimited sequences of values.

# : % -> NonNegativeInteger

#(x) returns the number of elements in tuple x

= : (%, %) -> Boolean if S has SetCategory

from BasicType

coerce : PrimitiveArray(S) -> %

coerce(a) makes a tuple from primitive array a

coerce : % -> OutputForm if S has CoercibleTo(OutputForm)

from CoercibleTo(OutputForm)

coerce : % -> PrimitiveArray(S)

from CoercibleTo(PrimitiveArray(S))

latex : % -> String if S has SetCategory

from SetCategory

select : (%, NonNegativeInteger) -> S

select(x, n) returns the n-th element of tuple x. tuples are 0-based

~= : (%, %) -> Boolean if S has SetCategory

from BasicType

CoercibleTo(OutputForm)
