496
EMOD, EMODP
[Operation]
:32-bit floating decimal point real number data or head number of the devices where the floating decimal point real number data is stored (real number)
:Decimal fraction digits data (BIN 16 bits)
:Head number of the devices where the data after break down into BCD will be stored (BIN 16 bits)
*1: Available only in multiple Universal model QCPU and LCPU
Function
(1) Dissociate the 32-bit floating decimal point data designated by into BCD type floating point format based on the
decimal fraction digits specified by , and stores the result into the area starting from the device designated by .
specifies the decimal fraction digits of the 32-bit floating decimal point real number data of .
In the example above, a decimal fraction digit is designated as shown below:
