In practice, sometimes we need to analyze the data. Recently we have encountered a situation where a series of abscissa are time, while the ordinate is the data of the recorded value, but the abscissa is not an offset record. that is to say, record

1. Wide conversion ()-widening Conversions Data is converted from a data type with a narrow data range to a data type with a wide data range, which generally does not cause data loss. Type Target types that can be converted without
