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:
: 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)
