 This code (a simplified version of the last test in t/op/number.t)

    set N31, 12.5
    print N31
    print "\n"
    null N31
    print N31
    print "\n"   
    end

 prints, as expected,

    12.50000
    0.00000

 when run normally, but

    12.50000
    2.00000

 when run under the JIT. However, the other null ops all seem to work 
 properly.
