Rails - Nov 2009 - What does /2 represent in a division calclulation ....hangs console

what does /2 or /5.5 represent to ruby?

in a division caclulation: x / 5.5

if you only put a space between x and the /, then
the console hangs
in irb it does this:

irb(main):014:0> x = BigDecimal("10.00")
=> #<BigDecimal:31a5ccc,''0.1E2'',4(8)>
irb(main):015:0> x * 5
=> #<BigDecimal:31a3760,''0.5E2'',4(16)>
irb(main):016:0> x / 2
=> #<BigDecimal:31a11a4,''0.5E1'',4(32)>
irb(main):017:0> x /2
irb(main):018:0/ x/2
=> #<BigDecimal:319e24c,''0.5E1'',4(32)>
irb(main):019:0> x /2.5
irb(main):020:0/

thanks

Looks like it thinks you''ve started a regular expression.
