Yep, Token.pow() takes an integer exponent.
However, I _think you can get access to Math.pow(double,double) in
the Expression Evaluator console:
>> pow(3.0,2.0)
9.0
>> pow(3.0,2.1)
10.0451085663051
>> pow(0.5,0.5)
0.7071067811865
>> pow(0.5,-0.5)
1.4142135623731
>> pow(-0.5,-0.5)
NaN
Note that ^ means integer power:
>> 2^2
4
>> 2^0.5
Exponent must have a valid lossless conversion to integer. Integer or
unsigned byte meet this criterion.
Use pow(10, 3.5) for non-integer exponents

Hi all,
I was trying to use the expression evaluator to calculate a double =
precision exponent, but realized that the pow method of the Token class =
translates the power function to a multiplication of the first argument =
by itself number of times as specified by the second (exponent) =
argument, and thus it is not supported for double precision exponents.
Is there another way to use the ParseTreeEvaluator to evaluate =
expressions that would allow this, or are there any plans to support it =
in the future?
Thanks a lot,
Efrat
