A faster pmax().
| x | A numeric vector. |
|---|---|
| a | A single numeric value. |
The parallel maximum of the input values. pmax0(x) is
shorthand for pmaxC(x, 0), i.e. convert negative values in x to 0.
This function will always be faster than pmax(x, a) when a is
a single value, but can be slower than pmax.int(x, a) when x is short.
Use this function when comparing a numeric vector with a single value.
