(Double precision) (ED*(P),ED/(P))
ED*(P),ED/(P)
Function
ED*
(1) Multiplies the 64-bit floating decimal point real number designated by by the 64-bit
floating decimal point real number designated by and stores the operation result at the
device designated by .
(2) Values which can be designated at , and and which can be stored, are as follows:
0, 2-1022 | Designated value (stored value) | < 21024
(3) When the operation results in -0 or an underflow, the result is processed as 0.
: Data to be multiplied/divided or head number of the devices where the data to be multiplied/divided is stored
(real number)
: Data for multiplying/dividing or head number of the devices where the data for multiplying/dividing is stored
(real number)
: Head number of the devices where the multiplication/division operation result will be stored (real number)
