| #1402 | fixed | darwinx8664 Makefile doesn’t specify OSVERSION when linking | ||
| Description |
In the darwinx8664 Makefile, the final link of dx86cl64 specifies |
|||
| #458 | fixed | decode-float and negative arguments | ||
| Description |
According to the spec, the following should be true for any floating-point number (multiple-value-bind (signif expon sign)
(decode-float f)
(* (scale-float signif expon) sign))
== f
http://www.lispworks.com/documentation/HyperSpec/Body/f_dec_fl.htm
If CCL> (decode-float -1.0d0) -0.5D0 1 -1.0D0 and thus: CCL> (let ((f -1.0d0))
(multiple-value-bind (signif expon sign)
(decode-float f)
(* (scale-float signif expon) sign)))
1.0D0
Probably we should ensure that the significand is non-negative in all cases. |

| #1216 | fixed | decode-float broken | ||
| Description |
decode-float seems to be broken, it returns some random 3rd value instead of the sign: [LinuxArm32, Odroid U3] Welcome to Clozure Common Lisp Version 1.10-dev-r16155M-trunk (LinuxARM32)! ? (decode-float pi) 0.7853981633974483D0 2 6.441148769597133D-232 Similarly on Windows X86 32Bit: Welcome to Clozure Common Lisp Version 1.10-dev-r16103-trunk (WindowsX8632)! ?
