range
Generates a set of numbers between two values
Syntax
y = range[from, to]
y = range[from, to, increment]
Attributes
from- the start of the range. Does not need to be an integer.to- the end of the range. Does not need to be an integer.increment- specifies the increment by which the elements are separated. By default, this value is1.
Description
y = range[from, to] generates a set of numbers starting at from and ending at to, in increments of 1. The range generated includes from and to.
y = range[from, to, increment] generates a set of numbers starting at from and ending at to inclusive, at a specified increment. The range generated will start at from and include as many elements as possible until the next element exceeds to. Depending on the chosen increment, this could potentially exclude to from the generated range.
Examples
Generate and display the integers between 1 and 10. In this example, y = (1, 2, 3, 4, 5, 6, 7, 8, 9, 10):
search
y = range[from: 1, to: 10]
bind @browser
[#div sort: y, text: y]
Generate and display the odd integers between 1 and 10. In this example, y = (1, 3, 5, 7, 9). Notice the set does not include 10 in this case.
search
y = range[from: 1, to: 10, increment: 2]
bind @browser
[#div sort: y, text: y]
We can use range and Eve’s join semantics to generate indicies for a grid of cells.
search
i = range[from: 1 to: 5]
j = range[from: 1 to: 5]
coordinate = "({{i}}, {{j}})"
bind @browser
[#div sort: coordinate, text: coordinate]
Will display:
(1, 1)
(1, 2)
(1, 3)
...
(5, 4)
(5, 5)
