SQL table reads 1234567891234567 -   CR displays 1234567891234570

My guess is that Crystal is limited to displaying 15 digits with accuracy, since rounding isn't being employed, and decimals don't matter, and the 'least significant' digit is being rounded.  It could also be how database is sending the number, perhaps it is in scientific notation.
 
I haven't come across this, but my reports don't have amounts that get that high...usually only into the billons 10^9 (6 digits smaller than the example)
 
Maybe someone else knows.

your guess seems to be correct...i can display correctly 123456789012345 (15 digits) however if i have 999999999999999 (15) i get 10000000000000000

I need to find at which point the figures get distorted.

the following number gets displayed correctly:999,999,999,999,995
this is where the rounding starts: 999,999,999,999,996 becomes 1,000,000,000,000,000
 
  99,999,999,999,999,999 (17 digits) will be rounded
999,999,999,999,999,999 (18 digits) will be converted to scientific number
 
it doesn't seem to comply with the sql data types
int: (2,147,483,647)
bigint (9,223,372,036,854,775,807)
money (922,337,203,685,477.5808)
 
it would be interesting to understand the concept behind the rounding.
