I wonder if the quotient of two numbers rounded to 13 or even 12 significant digits can have an error that would affect the 10-digit result. #-)

BTW, the Sandmath manual I got is revision 44_E ("this compilation revision 4.44.44 (really!)") from November 2012. Is this the current version that matches the Sandmath .mod file you sent?

I'll have to look a bit deeper into this. At the moment I get some strange results, e.g. floor(pi)=1 or ceil(0,5)=–1.
