Working in hex

ruby-talk
1

Hello, rubyists.

I need to do the following:

val = 0xe8b8 + (4 * 110).hex
= 0xe8b8 + 1b8
= 0xea70

Is there an easy way in Ruby of doing this?
I need to have the result in hex.

What about:

irb(main):001:0> val = 0xe8b8 + (4 * 110)
=> 60016
irb(main):002:0> val.to_s(16)
=> “ea70”

I think you are confused between the internal representation of a number
and its text representation.

val = sprintf(“0x%x”, 0xe8b8 + 4 * 110)

is one way to do it or

val = “0x” + (0xe8b8 + 4 * 110).to_s(16)

Hope this helps (and isn’t too ugly :slight_smile:
