Round 0.00208815 to 3 significant figures.

0.01

Given a decimal, move 2 decimal places and round to nearest digit. If the last number is not greater than .50 or less than .49 do nothing; if it is go right to left and find two numbers such as ( 1.2345)1= ( 1.23). The answer would be 1.24, because the first time we need to round we round any number ending in 5 up and any ending in less than 5 down; then we need to skip over the next set of numbers that end with 4 and take two numbers ending with 3 (2 3) = (2)6 which equals 26.
