num.step(limit[, step]) {|i| block } â selfnum.step(limit[, step]) â an_enumerator Instance Public methods Invokes block with the sequence of numbers starting at num, incremented by step (default 1) on each call. The loop finishes when the value to be passed to the block is greater than limit (if step is positive) or less than limit (if step is negative). If all the arguments are integers, the loop operates using an integer counter. If any of the arguments are flo
