Dividing inside iterations?

Ruby
#1

Hi

Learning R…

Is it possible to divide values while inside an iteration?

for example i’d like to do something like this:

h = [40,20,50,200]
h.each do |num,total| num / 24 = total
print “#{total} \n” end

as you’d expect, there is an error because of that ‘/’ and ‘=’ sign in
this iterator.

so since this isn’t possible what would be the best way to do what i’m
trying to do? or perhaps my syntax is wrong

thank you very much.

Yes, but in assignement the variable goes on the left.
h = [40,20,50,200]
h.each do |num,total|
total = num / 24
print “#{total} \n”
end

The “total” there doesn’t do anything; you’d just want:

h.each do |num|

total = num / 24
print “#{total} \n”

Of course this could also be:

puts num / 24

Or:

h = [40,20,50,200]
h.map{|num|num/24}.each do |num|
puts num
end

Or:

puts [40,20,50,200].map {|num| num/24 }
