Floating point library routines hang when converting to integer

Phil Pilgrim (PhiPi)

I've discovered that the ftrunc and fround routines in Float32, Float32A, and Float32Full hang when the argument is out-of-bounds for an integer. Here's my test code:

CON

  _clkmode      = xtal1 + pll16x
  _xinfreq      = 5_000_000

OBJ

  ser:  "Parallax Serial Terminal"
  flt:  "Float32"

PUB start | fp_number

  fp_number := $dd4495b3

  ser.start(9600)

  ser.str(string("Start.", 13))
  ser.dec(flt.ftrunc(fp_number))
  ser.str(string(13,"Done."))

BTW, the Spin version, FloatMath, does okay: it just returns zero for arguments that are out-of-bounds.

Phil, can you please post the "Float32" object here?

I believe this was the latest version (1.6)

Attached is the one I have -- same as Mike's: v.1.6.
