Hello MathGroup:

Originally I was confused also about imaginary exponents also but help
cleared that up.

Help for Power also has this sentence: "For certain special arguments,
Power automatically evaluates to exact values."

Does this imply that for irrational and real exponents, they are
"truncated" to rationals before they are evaluated?

Thanks in advance for any info on this.
