62.09 to the nearest whole number is 62

The steps for rounding is to underline the place to round to. Look at the number to the right. If that number is 5,6,7,8,9 then add one to the underlined number and drop the numbers to the right or fill in with zeros if it is between it and the decimal. 5.3425 is about 5.34 since the 2 is not 5,6,7,8,9.
688.3
It is 10 to the power of the_number_of_digits_between_the_4s_(excluding_the_4s_themselves)_plus_one; if the underlined 4 is to the right of the non-underlined 4, then make this count negative.eg, if the number is 1234564, then there are 2 digits between them (the 5 and 6), so the power is 2 + 1 = 3; then:If the first 4 is underlined it is 103 = 1000 times greater than the non-underlined 4If the second 4 is underlined it is 10-3 = 0.001 (= 1/1000) times greater than the non-underlined 4
If the fraction part of the mixed number is less than 1/2, round down. If it's 1/2 or greater, round up.
It is 2.
None of the numbers are underlined. In the number 56123, the 5 has a value of 50000, the 6 has a value of 6000, the 1 has a value of 100, the 2 has a value of 20 and the 3 has a value of 3.

If a coordinate is half way between a number, eg (2.3,74) then you round to the nearest whole number so it would be (2, 74) (round 2.5 to 3 not to 2, round 2.1 to 2 not 3 and round 2.7 to 3, this is because the number after the decimal place is either closer to one or the other)
