另外我看到一小段英文： ...the tenths digit in the decimal...
希望能幫我解釋一下...the tenths digit in the decimal...是要表達啥麼意思呀?

For example, in the numeral 10.34
the 0 is immediately to the left of the separator, so it is in the ones place;
the 1 to the left of the zero has a place value of one, and is in the tens place;
the 3 is to the right of the ones place, so it is in the tenths place; and
the 4 to the right of the tenths place is in the hundredths place.
And to the right, the digit is multiplied by the base raised by a negative (-) n. For example, in the number 10.34 (written in base ten),
the 1 is second to the left of the separator, so based on calculation it's value is,
n - 1 = 2 - 1 = 1
1 101 = 10
the 4 is second to the right of the separator, so based on calculation it's value is,
n = -2
4 10-2 = 4⁄100
