finding negative values

Is there any method with which I can find out if any value in an array is negative?

array1 = {1,2,3,4,5,6,7,8}
returns false

array2 = {1,2,3,4,5,-6,7,8}
returns true

Similarly, is there any way I can tell if they're all negative?

array1 = {1,2,3,4,5,6,7,8}
returns false

array2 = {1,2,3,4,5,-6,7,8}
returns false

array3 = {-1,-2,-3,-4,-5,-6,-7,-8}
returns true

Many thanks

Why not use a for loop and an if statement?

I could indeed. I was just wondering if there was a function or other neat trick...
