Math.min

[Radouane]

this code is from the http://www.angelfire.com/or/abhilash/Main.html :
System.out.println(Math.min(Float.NaN, Float.POSITIVE_INFINITY));
the result gives
NaN
1-can anyone explain to me why NaN ?
2- do we get questions like this in the exam?
Thanks

NaN-NotaNumber
u can get like these questions in the exams
when u trying to do any arithmetic operations like
0.0/0.0
0.0/-0.0
0/0.0
Math.sqrt(-1) // we cannot find sqrt for negative number
i will always give NaN
anything comparison with NaN always will return false
eg:
(Float.NaN==Float.NaN) will return false
OK bye,
