Data which will be converted into signed 32-bit
(S)
(1) The data specified with (S) is converted into a signed 32-bit integer value.
(2) The data range of (S) is -2147483648 to 2147483647.
(3) When (S) is a 64-bit floating-point type, its fractional portion is rounded down
before conversion is made.
(4) If (S) is a 32-bit integer type, its value is returned unchanged, with no conversion
processing performed.
(1) An operation error will occur if:
• The (S) data is outside the range -2147483648 to 2147483647; or
• (S) is an indirectly specified device and its device No. is outside the range.
