Round Significant Figures in TI-BASIC?


Question

hi all, i've been making some probability programs for my prob+stats class, and i want to make them as accurate as possible. is there any way that a TI-84 can round using significant figures? for example, if i used the round() command on the number 1.0873, and rounded it to two decimal places, the answer would be 1.09. if that same number were rounded using sig figs, the answer would be 1.087. that's what i need. does anyone know how to do it?

Multiple by 10^x (x=number of places after the decimal), round() it, then divide by 10^x

1.0873 * 10^3 = 1087.3

round(1087.3) = 1087.0

1087.0 / 10^3 = 1.087

If it has the count the sigfigs...that's a lot more complicated. Not sure how you would do that.
