Ruby How to iterate over a range but in set increments

Question

So I m iterating over a range like so    1  100  each do  n        n   1       n   2       n   3       n   4       n   5 end   But what I d like to do is iterate by 10 s   So in stead of increasing n by 1  the next n would actually be 10  then 20  30  etc etc

You can use Numeric step   0 step 30 5  do  num    puts  number is   num   end    gt  gt  number is 0    gt  gt  number is 5    gt  gt  number is 10    gt  gt  number is 15    gt  gt  number is 20    gt  gt  number is 25    gt  gt  number is 30

rng step n 1     obj   block     gt  rng   Iterates over rng  passing each nth element to the block  If the range contains numbers or strings  natural ordering is used  Otherwise step invokes succ to iterate through range elements  The following code uses class Xs  which is defined in the class-level documentation   range   Xs new 1   Xs new 10  range step 2    x  puts x  range step 3    x  puts x    produces   1 x 3 xxx 5 xxxxx 7 xxxxxxx 9 xxxxxxxxx 1 x 4 xxxx 7 xxxxxxx 10 xxxxxxxxxx   Reference  http   ruby-doc org core classes Range html

See http   ruby-doc org core classes Range html M000695 for the full API   Basically you use the step   method   For example    10  100  step 10  do  n        n   10       n   20       n   30           end
