matters needing attention If the calculation result is abnormal, such as "NAN" or "- 1. # IND "Or other non numbers, please check the input data; the reason for this error is that the data you input is inappropriate, which may cause the program to calculate meaningless formulas, such as calculation 。
Software features
1. Support scientific count method input
For example, you can enter 3.14e-5.6 to indicate 3.14 × 10 -5.6
2. The company can be switched at any time, and the result will be updated immediately after the company switching
3. Automatic error correction function
- If an error is entered, the system will automatically correct the error and feed back the result to the user:
- Delete the space, replace the period with a decimal point, and combine multiple decimal points into one. If you enter "5.. 6+9. 2", the system will correct it to "5.6+9.2".
- Remove the duplicate brackets. If you enter "56+(9 * 15/8)", the system will correct it to "56+(9 * 15/8)".
- If the calculation symbol is continuous, only the last one will be retained. If "56+/9" is entered, the system will correct it to "56/9".

Note: Although most errors can be corrected, there are still errors that cannot be checked. Please input carefully.
4. The interface is beautiful, the division is clear, and the calculation basis description is attached
5. Support mixed input of formula and function
No matter how complex the formula is, it can be calculated normally. The formula can include functions (trigonometric function, power, logarithm, etc.), and functions can also be nested in the function.
For example, to represent“ ”, you can enter "3.14 * 5/(pow (3 * 1-6, sin (30)))+8 * lg (5.2)"
6. Error prompt
If the data input is incomplete or the input function is illegal, an error prompt dialog box will pop up
