Additional information :-

✒ Significant figures are important to show the precision of your answer. This is important in science and engineering because no measuring device can make a measurement with 100% precision.

⚽ Rule of funding :-

• Non-zero digits are always significant

• Any zeros between two significant digits are significant

• A final zero or trailing zeros in the decimal portion only are significant

Example: -

• 500 or 0.632000 the zeros are significant .

• 006 or 0.000968 the zeros are not significant.
