#674 fixed (/ (complex 1d160 1)) overflows R. Matthew Emerson
Description

(/ (complex 1d160 1)) overflows

Answer should be #C(1.0d-160 -9.99988867182683d-321)

#673 fixed Please add :ccl-1.5 to *features* R. Matthew Emerson Dan Corkill
#671 invalid INTEGER-DECODE-FLOAT not consistent with DECODE-FLOAT Gary Byers Robert Dodier
Description

I get the following return values from INTEGER-DECODE-FLOAT. (Version 1.4-r13122 (WindowsX8632))

? (integer-decode-float 0s0)
0
-150
1
? (integer-decode-float 0f0)
0
-150
1
? (integer-decode-float 0d0)
0
-1074
1
? (integer-decode-float 0l0)
0
-1074
1

In contrast:

? (decode-float 0s0)
0.0
0
1.0
? (decode-float 0f0)
0.0
0
1.0
? (decode-float 0d0)
0.0D0
0
1.0D0
? (decode-float 0l0)
0.0D0
0
1.0D0

CLHS states that INTEGER-DECODE-FLOAT returns "the same last two values that are returned by decode-float". Observed behavior seems otherwise.
