all non zero digits are significant .2.zeroes betweenother significant.
What number are you talking about? Assume that all non-zero digits in a number are significant unless the zero is between two significant digits. For example, 0.00043 has two significant digits, 4 and 3. However, 0.00403 has three significant digits, 4, 0, and 3. The same goes for large numbers. 01,350,000 has three sig. digits: 1, 3, and 5. Be careful, though. If there is a decimal in the number, everything after the decimal is significant as well. For example, all eight digits in 45,000.000 are significant.
