Name:

verbosity global variable controlling the amount of information displayed by commands.

Usage:

verbosity = n : integer -> void verbosity = n ! : integer -> void verbosity : integer

Parameters:

n controls the amount of information to be displayed

Description:

verbosity accepts any integer value. At level 0, commands do not display anything on standard output. Note that very critical information may however be displayed on standard error.
Default level is 1. It displays important information such as warnings when roundings happen.
For higher levels more information is displayed depending on the command.

Example 1:

   > verbosity=0!;
   > 1.2+"toto";
   error
   > verbosity=1!;
   > 1.2+"toto";
   Warning: Rounding occurred when converting the constant "1.2" to floating-point with 165 bits.
   If safe computation is needed, try to increase the precision.
   Warning: at least one of the given expressions or a subexpression is not correctly typed
   or its evaluation has failed because of some error on a side-effect.
   error
   > verbosity=2!;
   > 1.2+"toto";
   Warning: Rounding occurred when converting the constant "1.2" to floating-point with 165 bits.
   If safe computation is needed, try to increase the precision.
   Warning: at least one of the given expressions or a subexpression is not correctly typed
   or its evaluation has failed because of some error on a side-effect.
   Information: the expression or a partial evaluation of it has been the following:
   (1.19999999999999999999999999999999999999999999999999) + ("toto")
