# Maximum

Keeps the running maximum value over an infinite interval, then returns the running value gathered during that interval.

Inputs

Syntax: Maximum(Event,Value,Reset,Preset)

Parameter | Description
--- | ---
Event | Specifies the update event on which to read the Value parameter. This parameter must be a reference to one of the following: The Image data structure in cell A1. A cell containing an Event function. A cell containing a Button function. Note: The Maximum function samples the state of a referenced value before that value is updated by any other function that depends on the specified Event.
Value | A reference to the source cell for the data stream on which a maximum is observed. Note: If you do not specify a cell reference, the function keeps the same value at each Event.
Reset | Forces the function to reset its internal register to the value specified by the Preset parameter.
0 = OFF (default) | The function continues to sample the Value parameter in the current data stream.
1 = ON | The function resets the output to the value specified by the Preset parameter on the next Event.
Preset | Specifies the initial value, and the maximum value to which the function is reset when the Reset parameter is ON, between -16777216 to 16777216. The default value is -16777216.

Outputs

Returns | The current running maximum of the Value parameter since the last Reset.
