Hi Folks,
My XSLT program computes this expression many times for different values of $x:
1 div (1 + math:exp(-$x))
Here is an equivalent expression:
math:pow(1 + math:exp(-$x), -1)
Which expression is better? By "better" I mean any one of these:
- produces more accurate results
- is faster
- is easier to understand, more intuitive
Or, are the two expressions equally good?
