Operand Description
S
Starting address of the device where the target data to be separated is stored or the constant
(data format: according to the operation unit)
D1
Starting address of the device where mantissa is stored (data format: according to the operation
unit)
Range (common to SF and DF): 0.5 or more, and less than 1.0 as absolute value)
D2 Starting address of the device where exponent is stored (data format: signed 32-bit integer)

(Note 1) Only 16-bit devices, and 32-bit devices can be modified (real number constants cannot be specified).
(Note 2) Index register (I0 to IE)
(Note 3) Can be specified only when the operation unit is a single-precision floating point real number (SF).
(Note 4) Can be specified only when the operation unit is a double-precision floating point real number (DF).
