[Setting data]
Setting data Description Data type of result
(S)
Data which will be converted into signed 64-bit
floating-point value
64-bit floating-point type
[Functions]
(1) The data specified with (S) is converted into a signed 64-bit floating-point value.
(2) If (S) is a 64-bit floating-point type, its value is returned unchanged, with no
conversion processing performed.
[Errors]
(1) An operation error will occur if:
• (S) is an indirectly specified device and its device No. is outside the range.
[Program examples]
(1) Program which converts the data of D0L into a signed 64-bit floating-point value
and substitutes the result to #0F
