[Description]
Tests if an expression is an integer.

[Explanation]
Returns 1 if the expression pointed to by <I>ptr</I> is an integer
or floating-point value; returns -1 for constants like <B><FONT FACE="Symbol">p</FONT></B> or <B><I>e</I></B>.
Returns 0 for everything else - this includes expressions like <CODE>ln(2)</CODE>,
<CODE>2<B><FONT FACE="Symbol">p</FONT></B></CODE>, or <CODE><B><FONT FACE="Symbol">&#214;</FONT></B>(2)</CODE>.
