The round() function only rounds decimal values. You can use this to emulate rounding to a near power of ten by dividing, rounding, then multiplying again. i.e. echo "<br>" . round(68500/1000) * 1000 . " ROUNDED"; You can also pass a second parameter to round() that indicates the precision to round to. If you pass a negative precision value, you can round to higher-order digits. For example, pass -3 to round to the nearest thousand. Having said that, based on the quote above, I believe this would be an incorrect solution to the problem. It sounds like the value is simply always rounded up to the nearest thousand, which means round() is not the function to use as it will sometimes round down. Instead ceil() should be used, as it always rounds up to the next whole number/integer. It lacks a precision argument, however, so the OP would need to use the divide-adjust-multiple trick you provided to make it work. That is, something like this: $newValue = ceil(68500 / 1000) * 1000 Numbers smaller than 1000 will need to be handled as an edge case, since this algorithm will "adjust" them to zero for you (same as when using round(), incidentally). If negative numbers are valid inputs, they'll also need careful review to ensure correct behavior. Hope that helps. -- Bob Williams ________________________________ Notice: This communication, including attachments, may contain information that is confidential.
