If there is 16#20 or 16#30 between the sign character and the first value which is not 0 in the
string, 16#20 or 16#30 is ignored when the string is converted into the binary number.

If 16#2E, which represents the decimal point, is ignored, the string in S should be within the
range between -32768 and 32767. For example, if the string is “1235.3”, users have to check
whether “12353” is within the range.
3. D$VAL:
The operand S occupies seven word devices at most.
The number of characters contained in the string in S should be within the range between 2
and 13.
If there is a decimal point in the string in S, 16#2E should be stored between the first character
after the sign character and the last character.
