I remember significant digits... Ahh, that takes me back to Introductory Physical Science in 8th grade :)
This doesn't quite work... But it might give you some ideas: Where INTVALUE ist he number you are getting the percentage of (ex. 93, 1.1, 14) and .75 is the percentage in the equation. <cfset intValue = 14 /> <cfset intDiv = (10 * (Len(intValue) - 1)) /> #(NumberFormat((intValue * .75 ) / intDiv, "0." & RepeatString(0, Len(intValue) - 1)) * intDiv)# Its rounding up... I can't remember the rules to sig-digits... .......................

This is a bit unusual. I want to figure out 75% of a given number and then round | floor | ceiling this number to a significant digit of the number. This is probably best described with examples. 75% of 93 = 69.75 floor to 60. 75% of 1.1 = 0.825 floor to 0.8 75% of 14 = 11.25 floor to 10 75% of .001 = 0.00075 floor to 0.0007 I am creating a series of charts from dynamic data. I want to set the minimum value of the chart based on a percentage of the minimum value being displayed. But I don't want to use values like 0.825 when my data is 1.1, ..9,1.3 ect. Does this make sense? I would also like to do a similar thing to set the top of the chart axis by adding 10% to the max value of the data series. -------------- Ian Skinner Web Programmer BloodSource www.BloodSource.org Sacramento, CA --------- | 1 | | --------- Binary Soduko | | | --------- "C code.
