I got the right answer but the question is tricky for me: "if [x] denotes the least integer greater than or equal to x"... does it concern only numbers like [1.5]=2; [-1.5]=-1;... or [1.4] will also be rounded to 2?

Hello from the GMAT Club BumpBot!

Thanks to another GMAT Club member, I have just discovered this valuable topic, yet it had no discussion for over a year. I am now bumping it up - doing my job. I think you may find it valuable (esp those replies with Kudos).

Hi everyone... This may sound strange but this is the first question I have ever come across [] to denote rounding up. I mistakenly treated it as || (absolute value) so obviously got the question wrong... Can I just confirm that this is a standard type of mathematical notation that is used on the GMAT? I have not seen this anywhere.... _________________

If you found my post useful, please consider throwing me a Kudos... Every bit helps

"[x] denotes to be the least integer no less than x" i can see why this is rounding down

but "If [x] is the greatest integer less than or equal to x"i dont see how thisis rounding down and why

"[x] denotes the least integer greater than or equal to x" why is this rounding up... i mean if theres only 2 of these i guess i could memorise but i'm trying to understand why...

please help. Ive been stuck on this interpretation for ages i dont want to just memorise it.

A quick comment. DO NOT memorize these definitions as they are not fixed. GMAT can change the definition of what the [x] does. Just try to understand what is the given definition.

Try to break it down in manageable chunks.

Case 1: "If [x] is the greatest integer less than or equal to x" ---> let x=4.4 what is the greatest integer LESS THAN or EQUAL to x ? Answer is 4 (5 will be GREATER THAN and NOT less than).You will get the equality when x = integer.

Thus, based on the definition of [x] above, [4.4] = 4 (you rounded DOWN ---> you went to a lower number).

Case 2: "[x] denotes the least integer greater than or equal to x" ---> let x =4.4 ---> based on this current definition, what is the LEAST integer GREATER or EQUAL to x? Answer is 5 (4 will not be correct here as 4<4.4). You will get the equality when x = integer.

Thus, based on the definition of [x] above, [4.4] = 5 (you rounded UP ---> you went to a higher number).

Do not memorize functional definitions as these definitions can change. Example, I can give you a question telling you that [x] denotes a function such that [x] =\(x^2\) etc.

Thanks for the explanation and time explain it to me. I thnk i understand it. I agree i should not memorise it. Thats why i was looking for an explanation.
