Okay thanks.  I'm going to set my own constant.
The math looks good too, although I'm just using for boundary conditions.

I was suprised not to find min or max functions either

looking for ...

someclass#min(x,y)
or
x.min(y)

I ended up using
x < y ? x : y

Then I stumbled upon...Enumerable's
[x, y].min

So I ended up using a mix of both as I was looping through arrays in some 
cases to get the min/max.
I'm presuming the latter is slightly slower for just a check of two numbers.
