How to round using significant figures
WebAlthough this may seem to defy logic, it is the way rounding works. For example, using the ROUNDDOWN function to round -889 to two significant digits results in -880. First, -889 is converted to its absolute value of 889. Next, it is rounded down to two significant digits results (880). Finally, the negative sign is reapplied, for a result of -880. WebRemember it like a group of three people walking on the road. The one in the front is leading the others. the one in the back is trailing them. So, the leading zeroes are the ones in front (like 0.052; the first two zeroes are leading) and the ones in the back are trailing (like in 56.00, the last two are trailing). Hope this helps!
