What is rounding a number to some specific place?
Rounding some number to a specific value is making its value simpler (therefore losing accuracy), mostly done for better readability or accessibility.
Rounding to some place keeps it accurate on the left side of that place but rounded or sort of like trimmed from the right in terms of exact digits.
The digit 5 acts as a limit.
if the right-sided digit to the digit where we've to round off is < 5, we keep it the same and make all right-sided values 0, and if the right-sided digit is > 5, then we make it increase by 1, and the rest of the right-sided digits become 0.
If the digit on right is 5, and after it, there is only zeros or no value,
then we round up (increase by 1, as we did in 347500 -> 34800 ) (Well there are many detailed rules of rounding)
