Subject: [ruby-talk:22376] Question on 'if' expression

The following was done on Windows 2000, Ruby 1.6.4
using irb.bat

I tried a 'if' statement format( see below) that I
used in 'C', assign a varible inside a 'if' statement.
The format does work, but I need to know if this is
part of the legal 'if' syntax. 

rb(main):004:0> x=2.1
2.1
irb(main):005:0> if (( xx=x.to_i) != 3 ) then
irb(main):006:1* puts "not ="
irb(main):007:1> end
not =
nil
irb(main):008:0> xx
2
