easy to miss
"Set8087CW sets both the control word in the floating point unit and the
variable Default8087CW declared in the system unit."

it should probably be a constant value for known state, anything that saves
then
restores set8087cw(olfpucw) will change the 'default'

system.pas initialises it to

var
  Default8087CW: Word = $1332;{ Default 8087 control word. FPU control
                                register is set to this value.
                                CAUTION: Setting this to an invalid value
                                          could cause unpredictable
behaiour. }
