To-pair - Function Summary


Summary:

(missing)

Usage:

to-pair value

Arguments:

value - The value argument.

Description:

Converts a value to a pair datatype.


    print to-pair [120 50]
    120x50


    x: 100
    y: 80
    print to-pair reduce [x y]
    100x80

This last line is done so often that the AS-PAIR function was created.

If you are performing a lot of xy pair math, you can also take a performance advantage of standard math operations on pairs:


    print 100x34 * 0x1
    0x34


    print 100X100 + 0x200
    100x300


    print 100x200 - 50
    50x150


    print 100x34 * 2
    200x68


    offset: 100x100 ; upper left corner
    size: 300x500   ; object xy size
    print offset + size ; the lower right corner
    400x600
