       Parse a numeric type from its string notation.
<synopsis>
numeric *PGTYPESnumeric_from_asc(char *str, char **endptr);
</synopsis>
       Valid formats are for example:
        <literal>-2</literal>,
        <literal>.794</literal>,
        <literal>+3.44</literal>,
        <literal>592.49E07</literal> or
        <literal>-32.84e-4</literal>.
       If the value could be parsed successfully, a valid pointer is returned,
       else the NULL pointer. At the moment ECPG always parses the complete
       string and so it currently does not support to store the address of the
       first invalid character in <literal>*endptr</literal>. You can safely
       set <literal>endptr</literal> to NULL.
