Subject: Math.sqrt(-1) doesn't raise ArgumentError

server> irb
irb(main):001:0> Math.sqrt(-1)
=> NaN
irb(main):002:0>

NaN == Not a Number

Why has sqrt behavier changed, when it hasn't for divisionbyzero?


irb(main):002:0> 3 / 0
ZeroDivisionError: divided by 0
        from (irb):2:in `/'
        from (irb):2
irb(main):003:0>
