Thanks.  Dumb question, but I'm kinda deep in the throes of the "suck" 
stage of learning Ruby.  The following also seems to work (at least for 
the purposes of reading in and writing formatted output):

irb(main):001:0> string="   1   45.3456   "
=> "   1   45.3456   "

irb(main):003:0> string.strip
=> "1   45.3456"

irb(main):004:0> string.split[1]
=> "45.3456"

irb(main):005:0> string.split[0]
=> "1"
