The dataView.getInt16() is an inbuilt function in dataView which is used to get a 16-bit integer at the specified location i.e, at byte offset from the start of the dataView. The range of 16-bit integer value is from 0 and 65,535 for unsigned and from ?32,768 to 32,767 for signed integer value.
Parameters: It has parameter byteOffset which is offset in byte and it says where to read the data from the beginning(start) of the view .
Return value: It returns 16-bit signed integer value.
Here as it can be seen that this function do not take float value when this float value is given to this function then it convert that value to integer value.
When there is no data to be stored, then it returns NaN i.e, not a number.
