RANGE

NAME

range : Generate an integer array with the range provided. Containing arithmetic progressions.

SYNOPSIS

range(stop);

range(start,stop[, step]);

DESCRIPTION

This function generate an integer array with the range provided. It is most often used in for loops. If the step argument is omitted, it defaults to 1. If the start argument is omitted, it defaults to 0. The full form returns an array of plain integers [start, start + step, start + 2 * step, ...]. If step is positive, the last element is the largest start + i * step less than stop; if step is negative, the last element is the smallest start + i * step greater than stop.

Note: all parameters have to be integers.

RETURN

This function returns an new array.

EXAMPLES

range(10,0); return []
range(10,20,-2); return []
range(10); return [0,1,2,3,4,5,6,7,8,9]
range(10,20); return [10,11,12,13,14,15,16,17,18,19]
range(10,20,2); return [10,12,14,16,18]
range(-10,20,3); return [-10,-7,-4,-1,2,5,8,11,14,17]
range(0, -10, -1); return [0,-1,-2,-3,-4,-5,-6,-7,-8,-9]
range(0); return []
range(1,0); return []
