[Chicken-users] pointer-f32-set!

[John]

Hey guys --

I just grabbed Chicken and was fooling around with it for a bit.  
Specifically, I was looking at the lolevel unit, and even more 
specifically, at arrays of 32 bit floating point numbers.  So, this is 
what I've got:

(define p (allocate 1024))
(pointer-f32-set! p 123.456)

The second line gives me the error 'bad argument type - not a fixnum: 
123.456.' 

I'm using Chicken 1.22 (what my distro has), but I don't see anything in 
the changelog that pertains to my question.  Is there some nuance of 
Chicken (or Scheme) that I haven't learned yet?

Thanks much,
John
