[Maxima-bugs] [maxima:bugs] Re: #4644 bfloat((x+1)/x includes unnecessary 1.0b0 factor

[Stavros M. <mac...@us...>]

I can't seem to reproduce that error in Maxima 5.48.1 SBCL 2.5.7.

~~~
map('nfloat,
    [1,1.0,1.0b0,2/3,x,1.0*x,1.0b0*x,2/3*x,
     x/y,2*x/y,2/3*x/y,1.0*x/y,1.0b0*x/y,
     %i*x,%i*1.0*x,%i*1.0b0*x,%i*2/3*x,
     %i*x/y,%i*2*x/y,%i*2/3*x/y,%i*1.0*x/y,%i*1.0b0*x/y,
     1+%i*x,1+%i*1.0*x,1+%i*1.0b0*x,1+%i*2/3*x,1+%i*x/y,
     1+%i*2*x/y,1+%i*2/3*x/y,1+%i*1.0*x/y,1+%i*1.0b0*x/y])
       => no errors
~~~
Maybe a bug has been introduced into `nfloat` recently?

Of course, it's hard to know what's a bug and what isn't because `nfloat` isn't documented!

bfloat((x+2)/x) => (1.0b0*(x+2.0b0))/x

What is the ``1.0b0`` factor doing there?

Set as priority 1 (which I hope means lowest, not highest) because this probably isn't doing any harm.
