Various versions of Extended on OS X, and AFAIK all PD versions on
Windows, have trouble with the [~] object.
It can be replaced with:
[expr~ $v1 $v2]
if there are two audio signals to be compared (as in a Pulse Width
Modulation application of this), or:
[expr~ $v1 1]

I think there's an easier way to do directory recursion in makefiles,
just using the export command (which sets variables globally,
accessible to all shell scripts).
So, if you have a top-level makefile, which sets variables according
to a makefile.in, you can export those variables. Then, build

Does anyone know how to tell, in c, if you're getting nans? It should be
easy enough in the dsp routine to replace nans with zeros.
It's just a question of detecting them in time. I remember you could do

okay, (on linux) you find math.h in /usr/include/ which includes a

there are three functions
int finite(double x) -- returns 1, if x is not NaN or inf
int isinf(double x) -- returns 1, if x is inf or -inf
int isnan(double x) -- returns 1, if x is NaN

Thanks, Charles,
For Windows, I found
int _isnan(double x) in float.h; it returns non-zero if x is NaN.
Also in float.h,
int _finite(double x) returns zero if the number is +- infinite or a
NaN, so that would seem to cover every possibility.
and
int _fpclass(double x) returns a specific code for
15 matches
