iBands mistake

 
double iBands( string symbol, int timeframe, int period, int deviation, int bands_shift, int applied_price, int mode, int shift)


What is wrong with non integer deviations, I wonder?

:: sigh ::
 

Just multiply the result of iBands() by a decimal to get fractional bands

Or, use iStdDev()... very similar thing. Result is 1 standard deviation, multiply it as you like.
