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)
