How many significant values are there in 700000

1 significant value

Explanation: Significant values in any number can easily be counted. You must begin at the first number above a zero. Any number above a zero to the right of it must also be counted. Zeros to the right of it can be counted, but only if there is a decimal.

Example #2: 40.05 has four significant values
Example #3: 200 has one significant value
