5.1 Arithmetic conversions
<a id='l2h-
331' xml:id='l2h-
331'
></a>
When a description of an arithmetic operator below uses the phrase
``the numeric arguments are converted to a common type,'' the
arguments are coerced using the coercion rules listed at the end of
chapter
<A href=
"datamodel.html#datamodel">3</A>. If both arguments are standard numeric
types, the following coercions are applied:
<LI>If either argument is a complex number, the other is converted
<LI>otherwise, if either argument is a floating point number,
the other is converted to floating point;
<LI>otherwise, if either argument is a long integer,
the other is converted to long integer;
<LI>otherwise, both must be plain integers and no conversion
Some additional rules apply for certain operators (e.g., a string left
argument to the `%' operator). Extensions can define their own
