What is 12064 round to?

Answer 1

It does not make sense to simply round a number without context or where there is no indication as to how much rounding is required. For example,

• if I needed to add 12064 to 1 trillion, I would round it to 0.
  
• if I needed to add it to 0.000023 then I'd leave it as it is.
• If I needed to divide it by 11 I'd choose 12100 since 12100/11 = 1100.
• If I needed to divide it by 12 I'd go for 12060 since 12060=12 = 1005.

Answer 2

The front end estimate is 12000. But estimating a single number, in isolation and without context, is a complete waste of time. It all comes down to the context of what needs to be done with the number.

If I had to add 12064 to 1 trillion, I would estimate it as 0.
If I had to add 12064 to 0.0000000001, I would use the number as given, or possibly the front end estimate. If I had to divide it by 5, I would estimate it as 12060, because 12060/5 = 2412. If I had to divide it by 11, I would estimate it as 12100, because 12100/11 = 1100.
