Ascii Character to Decimal Base 10 value

ruby-talk

Greetings all,

I would like to know how one might convert a letter such as "H" to its
corresponding ascii decimal value. On the flip side, how might I take
the decimal value and convert it back to the alpha-numeric
representation.

Is there something simpler or better than using the String class
each_byte() method? I seem to recall there is a simple way to do just
this, but can't find it in the docs.

Thanks,

Doug

PS: any ideas about doing this with Unicodes?

It's (to me) wildly non-intuitive.

> aString = 'B'
=> "B"
> aString[0]
=> 66
> aString[0..0]
=> "B"

?H #=> 72
?H.chr #=> "H"

Thanks all, that works well.
