Count how many significant figures are in a number and find which digits are significant.

This sig fig counter counts the significant digits or simply rounds a digit to the desired number of a significant figure. In the accepted answer there is the line round_to_11234243 10000000 That actually specifies 8. If a number expressing the result of a measurement eg length pressure volume or mass has more digits than the number of digits allowed by the measurement resolution. Enter whole numbers real numbers scientific notation or e notation.

Significant figures also known as the significant digits precision or resolution of a number in positional notation are digits in the number that are reliable and necessary to indicate the quantity of something. The number 00005 has only one significant figure and 10005 has 5 significant figures. The term significant figures refers to the number of important single digits 0 to 9 inclusive in the coefficient of expression in the scientific notation. For example 500 has 3 significant figures.
