Integer question

I'm having trouble understanding "the least integer greater than or equal to z" in the following question:

96. For all Z, [z] denotes the least integer greater than or equal to z. Is [x] = 0?

s1) -1 < x < -0.1
s2) [x + 0.5] = 1

What does "the least integer greater than or equal to z" mean? Can someone explain it to me in English? I read this over on last night and read it again today and I still can't comprehend the meaning to that statement.

Your help is greatly appreciated
