rounded up to the next $1000.

I am using report smith on sql , this is the result that I want

rounded up to the next $1000.

Example
88,200 = the report should print this 89,000.

44,000.21 = should print this 45000
44.000.00 = should print this 44000
45,200.00 = should print this 46000
44,700.00 = should print this 45000
round(m,n) does not work , only work for some
Thank you for taking the time to respond to my fist question
