When you apply a function to some piece of data, functions will often test to be sure you are giving it the right kind. For example, many math functions will require that you provide a number, so that the answer is actually valid. But, with Version 0.13, there is a twist. If you give any one of a dozen or so math functions a list of numbers, it will return the result of applying that function to all list elements. And in fact, it will work with a nested list as well. So:

Print(Ln(3.5) )

Print(Ln([1,3,4,6,6,7,8]))

Produces values:

1.25276

[0, 1.09861, 1.38629, 1.79176, 1.79176, 1.94591, 2.07944]

This is actually an old feature that worked five or eight version ago, but it fell by the wayside at some point and was never re-implemented. In fact, some functions that take TWO arguments will work as well, recursing on the first argument. So

LogN(1,10)

LogN([1,10,100],10)

Produce results:

0

[0,1,2]

Importantly, you don't provide a list for the second argument.

This only currently works for a set of math-related functions:

ˆ Log10

ˆ Log2

ˆ Ln

ˆ Exp

ˆ Sqrt

ˆ Tan

ˆ Sin

ˆ Cos

ˆ ATan

ˆ ASin

ˆ ACos

ˆ DegToRad

ˆ RadToDeg ˆ

Round ˆ

Floor ˆ

Ceiling

ˆ AbsFloor ˆ

Sign

ˆ Abs

And a handful of two-parameter functions:

LogN ˆ Pow ˆ NthRoot

In the future, it could be enabled for more functions (let me know!), and there may be a way to make the functionality available through a new PEBL function; but all this would take some careful thought and planning.

So, keep an eye out for additional new functions that are available in PEBL 0.13
