Function definition: (Copy & paste into FileMaker's Edit Custom Function window)

This function finds the next highest "round" number, based on whatever factor of ten the original number is based. For instance, 11 becomes 20; 200 becomes 300; 0.4 becomes 0.5; and -120 becomes -100. (In this function, a "round" number is regarded as an integer multiplied by some power of ten.)

This function might be useful for determining a chart's maximum scale (as in xmCHART): for example, if the maximum data point is 428, this function returns 500 as an appropriate chart maximum. It bumps already round numbers up (200 goes to 300), on the principle that a chart's data point should never lie directly on the maximum. (An exception is made for zero.)

This works well with number less than 100,000. If you have number say 101,000, the next round number return by this function is 200,000 which it way too large. The xmCHART does not looks good with this large maximum value | ||
