Appeal No. 2000-2225
Application 08/998,617
Representative claim 1 is reproduced as follows:
1. A computerized method for distinguishing an ordinary
binary floating point number from an extraordinary binary
floating point number, said computerized method comprising:
adding 1 to a B-bit biased exponent of a binary floating
point number to produce a (B+1)-bit augmented exponent;
sign-extending said (B+1)-bit augmented exponent to
produce a (B+n)-bit transformed exponent; and
testing said (B+n)-bit transformed exponent to determine
if said (B+n)-bit transformed exponent is less than 2 to provide
an indication whether the binary floating point number is
ordinary or extraordinary.
The examiner relies on no references.
Claims 1-10 stand rejected under 35 U.S.C. § 101 as being
directed to nonstatutory subject matter in the form of a
mathematical algorithm.
Rather than repeat the arguments of appellant or the
examiner, we make reference to the briefs and the answer for the
respective details thereof.
