/****f* AWK/qse_awk_rtx_strtonum
* NAME
* qse_awk_rtx_strtonum - convert a string to a number
* SYNOPSIS
/**
* The qse_awk_rtx_strtonum() function converts a string to a number.
* A numeric string in the valid decimal, hexadecimal(0x), binary(0b),
* octal(0) notation is converted to an integer and it is stored into
* memory pointed to by @a l; A string containng '.', 'E', or 'e' is
* converted to a floating-pointer number and it is stored into memory
* pointed to by @a r. If @a strict is 0, the function takes up to the last
* valid character and never fails. If @a strict is non-zero, an invalid
* character causes the function to return an error.
*
* @return 0 if converted to an integer,
* 1 if converted to a floating-point number
* -1 on error.
