■Description, data type of result
Setting data Description
(S) Data which will be converted into signed 64-bit floating-point value
Processing details
• The data specified with (S) is converted into a signed 64-bit floating-point value.
• If (S) is a 64-bit floating-point type, its value is returned unchanged, with no conversion processing performed.
Operation error
An operation error will occur if:
• (S) is an indirectly specified device and its device No. is outside the range.
Program example
■Program which converts the data of D0L into a signed 64-bit floating-point value and
substitutes the result to #0F
#0F = FLOAT(D0L)
#3 #2
#0F K-1.0
