math.rounding question

hi,
who knows how i make a rounding of an EMA to a wished format ie :

121.25 instead of 121.2469857...

i want to use my EMA-value in an indicator but want it rounded to 2 numbers behind the point - like 121.25 instead of 121.2469857
if i use an EMA in my chart it is always set to the ticksize of the instrument - but if i use it in an indicator the value is given in a long number.
i dont wanna transform it in a string - i need a double value.
any ideas ?
Thanks in advance.

Multiply it by four, then round it, then divide it by four.

You may want to consider using Round2TickSize. It can be used on more than just price. It will round any number to the nearest Instrument Tick Size. For example if the indicator is placed on an ES chart the ES Tick Size is .25. So using this example will round any number to the nearest .25. There may be some issues doing it this way but I have not found them.

Indicator.Set(Instrument.MasterInstrument.Round2TickSize(value to be rounded);
