MOTOROLA
Destination Register field—Specifies the destination floating- point data register. If R/
Opmode field—Specifies the instruction and rounding precision.
0000100 FSQRT
1000001 FSSQRT Single-precision rounding specified.
1000101 FDSQRT Double-precision rounding specified.
M = 0 and the source and destination fields are equal, the input operand is taken
from the specified floating-point data register, and the result is written into the
same register. If the single register syntax is used, Motorola assemblers set the
source and destination fields to the same value.
