Bug? Power function errors.

[tigrot]

Hi everybody,
Seems power function's error strikes again. Many years ago I wrote an epilator firmware on a mega32 Atmel in assembly. I found some issue in power function. The results were non ok. Now I find that power(10,2) gives 99 as result. Maybe library is the same?
Advice: avoid power functions!. You can live without...

How did you test it?
In B4A the result is 100!

Tested on Arduino Mega:

Sub Process_Globals
   Public Serial1 As Serial
End Sub

Private Sub AppStart
   Serial1.Initialize(115200)
   Log("appstart")
   Log(Power(10, 2))
End Sub

The result is 100.

I was not able to reproduce the error. The power was inserted in a larger function. I used to convert a string to an integer value, but in case of number larger than 99 the result was always 1 less the expected result.
I have already solved using an incremental multiply, but it was a surprize when I saw the log with value 99!
