    89.7

    Explanation:

    First we have to look at the right of the digit which is going to be round. If it is 5 or greater than 5 than the number left to it should be increased by one.

    For example

    In given number 89.667 after three digits 8, 9, 6 the next digit is 6.

    So in order to round the number to three digits 6 will rounded to 7 and value becomes 89.7

    If the digit next to rounded digit is less than 5 than number will rounded as,

    For example:

    56.42

    Rounded to three digit it will be 56.4.
