On NT's EMA code

[binwang2]

Hi NT experts,

I need help to understand the logic of official NT EMA code:
Value.Set(CurrentBar == 0 ? Input[0] : Input[0] * (2.0 / (1 + Period)) + (1 - (2.0 / (1 + Period))) * Value[1]);

Is it equivalent to:
if (CurrentBar ==0)
{
Value.Set(Input(0));
}
else
{
Value.Set(Input[0] * (2.0 / (1 + Period)) + (1 - (2.0 / (1 + Period))) * Value[1]);
}
In other words, the formular applies to all bras except for the 1st bar?
Any suggestions are welcome.

binwang2, correct on the first bar assign the Input value, on the following bars, calculate the EMA values as per the standard formula.
