occur. When its value is off, these warnings are suppressed.
- This mode depends on a verbosity of at least 1. See
verbosity for more details.
- Default is on when the standard input is a terminal and
off when Sollya input is read from a file.

If safe computation is needed, try to increase the precision.
Warning: rounding has happened. The value displayed is a faithful rounding to 165 bits of the true result.
> roundingwarnings = off;
