How to round to 2 decimals in bash like MS Excel does?

I spent hours in searching how to round "floating numbers" in BASH but couldn't find any correct! solution :( If I put these numbers to Excel, then I will receive the correct results after rounding to 2 decimals: 3.314 -> 3.31 3.315 -> 3.32 8.124 -> 8.12 8.125 -> 8.13 How to have the exact results in BASH? I tried with printf and awk but don't have the same result prompt> printf '%.*f\n' 2 8.125 8.12 prompt> echo '8.125' | awk '{printf("%.2f\n", $1)}' 8.12
