9.70 SegmentBinding

The SegmentBinding type is used to indicate a range for a named symbol.

First give the symbol, then an = and finally a segment of values.

x = a..b

\[\]

x=a..b

_{Type: SegmentBinding Symbol}

This is used to provide a convenient syntax for arguments to certain operations.

sum(i^2, i = 0..n)

\[\]

_{Type: Fraction Polynomial Integer}

draw(x^2, x = -2..2)

The left-hand side must be of type Symbol but the right-hand side can be a segment over any type.

sb := y = 1/2..3/2

\[\]

y=(12)..(32)

_{Type: SegmentBinding Fraction Integer}

The left- and right-hand sides can be obtained using the variablevariableSegmentBinding and segmentsegmentSegmentBinding operations.

variable(sb)

\[\]

y

_{Type: Symbol}

segment(sb)

\[\]

(12)..(32)

_{Type: Segment Fraction Integer}
