# 10 numbers in between 2 numbers

How can I get an array of 10 numbers in between two numbers?

(1…500).to_a

How can I turn the above into an array of ten numbers in between 1 and
500 (including 1 and 500)?

I guess it depends on which ten numbers you want, but here’s one way:

(1…500).enum_for(:step, 50).to_a
=> [1, 51, 101, 151, 201, 251, 301, 351, 401, 451]

I’m confused… aren’t there a lot more then 10 numbers between 1 and
500? Are you asking for a random sampling or???

10 numbers randomly, or spread out evenly (ish), such as 1, 50, 100,
150, 200, 250, 300, 350, 400, 450, 500 (though that’s 11 and not
exactly even). Can you elaborate?

Sorry everyone, yes 10 numbers and dates spread our evenly. Thanks for
the replies!

Yeah, the end numbers need to be included in the array of 10.

Requirements: 10 numbers, evenly distributed, first and last numbers in
the array.

require ‘pp’

first, last = ARGV[0].to_f, ARGV[1].to_f
numbers = []
incr = (last - first) / 9.0
n = first
10.times do
numbers << n
n += incr
end
pp numbers

Awww, you didn’t say the final array didn’t have to contain integers
