Re: Rounding up to nearest 1000

say the number is 1455.

1455 - 1 = 1454, divide by 1000 = 1. Add 1 = 2.  Mult 1000 becomes 2000

1000 - 1 = 999, divide by 1000 = 0, plus 1 = 1, times 1000 = 1000

1999 - 1 = 1998, divide by 1000 = 1, plus 1 =2, mult 1000 = 2000.

Adam,

I'm trying that out using my trusty calculator, and I'm not ending up
with a round number.

Say I want to round 1461 up to the nearest thousand, which would be
2000.
So N is 1461 and S = 1000

Temp = 1461 + 1000/2
Temp = 1461 + 500
Temp = 1961
Result = (1961/1000) * 1000

Result = 1961 ? Did I do something wrong ?
