significant digits for decimals
MrShorty wrote...
.... If not, then the easiest way I know of to get three sig figs is to use a scientific number format (0.00E+0), but a lot of people are either uncomfortable with exponential notation or for some other reason it isn't desirable. A function like ROUND(A1,INT(LOG(A1)-2) will return a number to three .... Arguably simpler to use scientific notation as an intermediate step. =--TEXT(A1,"0."&REPT("0",SigDig-1)&"E-0") or hardcoded for 3 significant digits =--TEXT(A1,"0.00E-0") This approach also handles nonpositive numbers. |
