Operation:
When the float instruction is used without the float
flag (M8023 = OFF) the source data (S) is
converted in to an equivalent value stored in float
format at the destination device (D).
Please note that two consecutive devices (D and
D
+1) will be used to store the converted float
number. This is true regardless of the size of the
source data (S), i.e. whether (S) is a single device
(16 bits) or a double device (32 bits) has no effect
on the number of destination devices (D) used to
store the floating point number. Examples:
