Round to double float

[aliser]

Hi,

I am working with pixel library and working on patches for RGBa adjustments and picture manipulation. Therefore I need to round numbers to double floats. How do I do it?

I hope someone can help me here.

All the best!

Hi Aliser,

If i am not mistaken, you can set the variable read-default-float-format to double-float like that (standard CL setf) :

> (setf  *read-default-float-format*  'double-float)

That is, in a lisp file, or in a lispfunction like this:
