<title>Description</title>
<para>Sets the current printing format with the parameter
<literal>type</literal> ; it is one of the following :</para>
<variablelist>
<varlistentry>
<term>"v"</term>
<listitem>
<para>for a variable format (default)</para>
</listitem>
</varlistentry>
<varlistentry>
<term>"e"</term>
<listitem>
<para>for the e-format.</para>
</listitem>
</varlistentry>
</variablelist>
<para><literal>long</literal> defines the max number of digits (default
10). <literal>format()</literal> returns a vector for the current format:
first component is the type of format (1 if <literal>v</literal> ; 0 if
<literal>e</literal> ); second component is the number of digits.</para>
<para>In the old Scilab versions, in "variable format" mode, vectors
entries which are less than %eps times the maximum absolute value of the
entries were displayed as "0". It is no more the case, the clean function
can be used to set neglitible entries to zeros.</para>
