hi

For all z, [z] denotes the least integer greater than or equal to z.
so if [x+0.5] =1, x+0.5 has to be between 0 and 1 including 1..
if x+0.5 is between -0.999999 and 0, inclusive, then [x+0.5] =0..
basically what ever is betwen [] takes the higher integer value or same value if it is integer...

Do we need to apply round up concept for these kind of questions ?
For eg, if some integer , say x , falls within 0.1 to 0.4 — we can say it’s nearly equal to 0
And on the other hand if x falls between 0.5 to 0.9 we say it’s nearly equal to 1 ??

At times , I get confused whether I can apply round up concept here also ?

Kindly advice

Any help on what does -0.1 become? 0?
