One is certain and the other in uncertain.

if I understand your question, the smallest six-digit number is 100 000. Perchance it is also even. And here I'm uncertain of your wording - but: - And it is two times fifty thousand.
Certain digits refer to the digits in a numerical value that are known with complete accuracy, as opposed to uncertain or ambiguous digits. In measurements, certain digits include all the digits that can be confidently reported based on the precision of the measuring instrument, plus one estimated digit that reflects the measurement's uncertainty. For example, in the measurement 12.3 cm, the digits '1', '2', and '3' are certain, while the last digit is considered uncertain.
490 to 2 s.f. Note that when the significance is uncertain, you must specify it (s.f. is an abbreviation of significant figures). You can also underline the last significant digit: 490
An uncertain digit is a digit in a measurement that is estimated or not completely reliable, often due to limitations in the measuring instrument or the precision of the measurement.
One is certain and the other in uncertain.
A term Significant Figure refers to all the certain digits and one uncertain digit in a measurement.
the last number.
The last digit is insignificant figure or uncertain .
At most 1.
Consider it a convention. Basically, it doesn't make much sense to register many more digits after a digit that is uncertain. Another common convention is to enclose uncertain digits - often the last two digits shown - in parentheses, for example, 6.67384(80)×10−11 for the gravitational constant in SI units.,
The uncertain figure of 2.423 would be the thousandths place, as it is the last digit given after the decimal point and represents the smallest decimal place indicated.
significant figures
43.52 centimeters (cm) has four significant figures. The final figure in place four of '2' is the most uncertain. This is because the measurement device or calculation may have originally been 43.516 through 43.519 before rounding or due to instrumentation uncertainty.
