on format/informat?

[milts]

i have a value of 171,775,417,252.01600 with a format of 25.5. How come when I change the format to 25.3 the decimal value becomes .017? And then when I changed the format to 25.5 again it again got the .01600 value. How does SAS round decimal numbers?

Thanks!

FYI

the value is a result from a calculation.

Thanks!

I don't know the answer but it might help to replicate the behavior if we see the actual value please the print number using HEX16 and post that.
