Numeric data

Right!

Numerical data (metric data) are observed values measured on a digital scale, and the results are expressed as specific numerical values. Most of the data processed in reality is numerical data. ^[1]

Such as the income of 300 yuan, age 2 years, 100 test scores, weight 3 kg, etc., these values are numerical values. For numerical values, we can directly use arithmetic methods for summary and analysis, while other types of values require special methods to handle.

Numerical data is a data type that indicates quantity and can be used for numerical operations. Numerical data consists of numbers,

Numerical data in Microsoft Excel software often represents the quantity of certain data types, such as date, time, Arabic numerals, length, height, weight, and so on. In Excel 2003, the maximum positive number of a numerical number can be up to the 307th power of 9.9 * 10, and the smallest negative number can be up to the 307th power of -9.9 * 10, but its precision can only be accurate to 15 digits. When the number in the Excel2003 cell exceeds 15 digits, the digits after the 15th digit will be replaced with the number 0. This limitation has not been breached even in Excel 2007. Therefore, when the user needs to retain more than 15 accurate numbers (such as entering an 18-digit ID number or a bank card number greater than 15), the cell data type needs to be set to "text" format. ^[2]

In Solver, the final Answer Report that is the calculation result report, the meaning of the type value is the value of the cell in the current row (that is, the value of all the variables that meet the requirements and goals), and the limit of the variable (The upper or lower limit can be adjusted). For example, if the value of the variable reaches the maximum or minimum value of the given limit, then the type value of the variable is 0. If the required variable is 1000 and the condition is given a limit of 2500, then The type value is 1500.
