Abstract
1388595 Digital calculator ING C OLIVETTI & C SpA 19 April 1972 [22 April 1971] 59391/72 Divided out of 1388593 Heading G4A The subject matter of this Specification is identical with that of Specification 1,388,593, but the claim relates to a computer having an arrangement for separating a number having integral and decimal parts representing respectively the exponent and mantissa of a floating point number into its exponent and mantissa parts which are stored in respective registers.
