math.round

Rounds number to the nearest whole number and returns an int. Pass a precision as well and the function keeps decimal places instead: the result is then a float, not an int. That change of return type is the practical difference between the two forms, so pick the form by what you need back - an int to count with, a float to plot. In the series form the precision is itself series, so how many places you keep can differ from bar to bar.

math.round(const float number) → const int

math.round(const float number, const int precision) → const float

math.round(input float number) → input int

math.round(input float number, input int precision) → input float

math.round(series float number) → series int

math.round(series float number, series int precision) → series float

math.round(simple float number) → simple int

math.round(simple float number, simple int precision) → simple float

Returns const float or const int or input float or input int or series float or series int or simple float or simple int — An int in the argument’s form from the one-argument form; a float in the arguments’ form from the precision form.
