Manual Method
You guys can use the above-mentioned website. It will save your precious time and efforts. Else, you can also use the manual method. You can calculate the Significant Figure by a simple method. Suppose there is a number 2.256. Now consider the digits after the decimal point. Count the digits. If the last digit is greater than 5, increase 0.1 in the previous digit. Follow the same process on all the digits till the point value. In the end, you will get a Significant Figure number.
This is one example. Let us take another example. Let us say that the expression is 25.6890 and you want to find the Significant Figure for this number. When you round off this number then the value shifts to the left side of the digits in the decimal section. This means that 8 becomes 9. After that, 6 become 7, and the final answer will be 26. Here the number of Signiant digits are 2 (as 26 contains 2 and 6). Here in this answer (i.e. 26) the decimal numbers are zero.
This method is a bit lengthy and complex because when you are going find the significant figure manually, it will take you a lot of time, along with your lot of efforts. So, when you are doing your homework or any assignment, it’s better to use the above-mentioned website. It will not only save your time but also save your efforts.
