(2) Floating-point operation instructions for the Universal model QCPU
TableApp.30 lists floating-point operation instructions for the Universal model QCPU.
Specifications of the single-precision floating-point operation instructions are compatible with those for
the High Performance model QCPU.
Floating-point data can be converted mutually between single precision and double precision using
instructions in
TableApp.33.
