OpenEuphoria

1. Are EuBins supposed to be functional builds?

The reason I ask is that I downloaded eubin-2015-10-11-16462e686646+.zip from /eubins/windows/4.1.0/64-bit. euc and eui run okay when lauched without parameters but do nothing when given a script to work through, viz

>type bin.ex 
include std/math.e 
include std/convert.e 
 
function Bin(integer n, sequence s = "") 
  if n > 0 then 
   return Bin(floor(n/2),(mod(n,2) + #30) & s) 
  end if 
  if length(s) = 0 then 
   return to_integer("0") 
  end if 
  return to_integer(s) 
end function 
 
printf(1, "%d\n", Bin(0)) 
printf(1, "%d\n", Bin(5)) 
printf(1, "%d\n", Bin(50)) 
printf(1, "%d\n", Bin(9000))

I tried all eubins for 64bit Windoze up to the first 2015 eubin, and they all failed the same way.

There's something wrong with the scanner. I tried running buzz.ex and it failed on both 64bit Windoze and 64bit Linux/GNU.

However, as a workaround, I was able to get this working on both by changing std/mathcons.e

Change

TWOPI     = 6.28318_53071_79586_47692, 

to

TWOPI = 2*PI, 

Change

LN10      = 2.30258_50929_94045_68401, 

to

LN10 = log(10), 

And finally, change

RADIANS_TO_DEGREES   = 57.29577_95130_82320_90712, 

to

RADIANS_TO_DEGREES   = 180 / PI, 

It looks like this is related to the recent fenv / floating point changes, as I was able to get 64bit Linux/GNU to work with an unmodified std/mathcons.e by instead changing std/fenv.e to disable it (making sure that the C routine ids were always -1).
