# 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.

thanks
