@item expr_int_format, eif
Evaluate the expression's value and output as formatted integer.
First argument is expression to be evaluated, same as for @var{expr} function.
Second argument specifies output format. Allowed values are 'x', 'X', 'd' and
'u', they are treated exactly as in printf function.
Third parameter is optional and sets the number of positions taken by output.
Effectively this allows to add padding with zeros from the left.
