This is a simple issue, but the fix I used seems like a hack to me.
float foo=0.0;
(assign a value to foo)
if abs(10*foo >100)
cntxcs = cntxcs+1;
Here's the deal. I want to know if abs( foo) is >1 0, but I finally looked close ennough to see that abs deals with ints -- explained my strange issue of short counts,
Multiplying by 10 gives me the int that I need, but I really don't like it.
Somebody please show me the simple and clear way to do this.
Thanks,

Please, make an effort to at least balance your braces. This is unreadable.

`1 0` is supposed to be `10`, right?
Then just do
if (foo < -10 || foo > 10) ...
no need to involve `abs`.
Or you can simply do
if ((foo >= 0 ? foo : -foo) > 10) ...
just to see which version produces a better code.

This is not entirely accurate. It actually depends on the language. What language are you talking about: C or C++?
In C `abs` indeed deals with `int`. But C also has `fabs` and `fabsf` that work with `double` and `float` respectively. You can do
if (fabsf(foo) > 10) ...
but it might end up being less efficient than the previous variants.
In C++ `abs` is overloaded and can deal with all arithmetic types by itself.
Multiplying by 10 gives me the int that I need, but I really don't like it.
Then don't.
Then again there is also an issue of your `foo` being a `float`. Why `float`? Does it have to be `float`? Floating-point types are quite "heavy", you know. Maybe you can use fixed-point format from the very beginning, i.e. use an integer variable that is already "multiplied by 10" internally? But there's no way to say say without knowing the context.

Thanks for the plethora of comments. I apologize for the poor post. A coworker once referred to me as a dyslexic typist -- and it's pretty true.
foo ( not its real name :) ) pretty much has to be a float
Thanks again,

That sounds suspicious---what makes you say that?
