Program much 1620 SPS using Monitor II?
*NOISE DIGIT n
was an SPS control record when using the floating-point subroutines.
It was stored in the system table area on disk. Oddly, this was not
offered as an option on FORTRAN II-D.
CDC 6000 series machines had three sets of floating point
instructions. Nomalized, un-normalized and "rounded". Rounded would
introduce non-zero normalization fill, which varied depending on the
operation.
