How to do typecasting?

ruby-talk
1

hi,

is there a way to typecast values? 
if I have an array with numbers, and I want to perform sting type
methods on it.

a = [1,2,4345,3]
a.each { |l| print l.length }
to produce
>>  1141

besides defining a as ["1","2",etc], what options are there?
···

–
“Then we typed the G, and the system crashed”…

Try this fix:

a.each {|l| print l.to_s.length }

a.each { |v|
print v.to_s.length
}

a = %w[1 2 4345 3]
=> [“1”, “2”, “4345”, “3”]
