As the string representation of the formula to designate the rounding?

Let's say I have a formula
c = a + b
thus a is the result of rounding x/y to hundredths
need 1 line to record this. Display to the user that would show how the computations. Can't remember how to write the rounding. It is generally written as?
Clarify how to count it I understand how it is in the line to designate, for example:
c = ( x / y ) + b
How to identify what is x / y rounded to hundredths

Solution
Standard characters only have to be rounded to the nearest whole number:
⌈x⌉ is rounding up (ceil)
⌊x⌋ rounding down (round)
[x] is the rounding to the nearest whole number

Looks like there is anything suitable.

Solution
You can use error. The amount is rounded off to one significant figure error. So 8.78±0.01 is equivalent to rounding to the hundredths.
