set *read-default-float-format* to 'double-float

Opened this issue · 5 comments

I'm too new at lisp to be suggesting such changes, but I was reading common lisp recipes and Edi Weitz suggests setting this in .sbclrc. It seems like a sensible default, maybe it makes sense for ciel to set this by default?

+ 1 I was hit by single floats already.

Let's not rush and be sure there would not be surprising side-effects, maybe especially in popular third-party libraries. Being a suggestion in CL Recipes gives it a lot of weight though!

thanks

sounds good, I've got it set in my .sbclrc and will report if I run into any issue with it

well it caused the first issue, I was building ciel again from scratch and got an error when it builds nodgui:

[package nodgui-user].......While evaluating the form starting at line 12, column 0

Type HELP for debugger help, or (SB-EXT:EXIT) to exit from SBCL.

A fix is merged into nodgui and now CIEL builds and seems to work fine with (setf *read-default-float-format* 'double-float)

Thanks! I'll try it a bit in my day-to-day and all projects.
