Abstract
In a floating point digital differential analyzer, multiplication and division of constants are carried out by an adder which truncates a summation SDY.sub.i of l secondary increments calculated by ##EQU1## into a third increment having an n-bit mantissa including a sign bit, and an integrator for carrying out an integration of R.sub.i :=R.sub.i-1 +Y.sub.i .multidot..DELTA.X.sub.i -.DELTA.Z.sub.i irrespective of a value of a first increment .DELTA.X.sub.i to generate .DELTA.Z.sub.i from R.sub.i.
