[positioning of this program]

This procedure is positioned as: voice + simple + common + convenient + free software.

Therefore, this program does not intend to provide voice switch function. If voice function is not required, it is recommended to use the calculator that comes with Microsoft.

[original intention of development]

Most of the calculator software with voice is charged or cracked, but mine is free at first.

Second, open source, that is, there is no back door, you can also diy.

[shortcomings of this procedure]

After adding the voice function, the speed of the program is bound to slow down a lot.

For win7, you can go to Control Panel-> speech recognition-> text-to-speech conversion and adjust the speed to make it slightly faster.

[reliability]

Although "this calculator miscalculates the number caused by any loss, not responsible!" But scripting languages call the system library to complete the operation.

The reliability is very good. Basically will not regard jubilation as unreliable as a gray wolf.

This procedure is to call the. Net library to complete the operation.

[precision]

The calculation results of this calculator have two kinds of accuracy, which are:

29 places (before plus or minus decimal point + after decimal point)

Automatic selection within languages from 15 to 29 digits (before plus or minus decimal point + after decimal point)

You can change it through the calculator's settings button.

The 29-bit accuracy is better, of course, but it is calculated (1-bit 3) * 3-bit 0.999999. It is suitable for situations where the calculation result is relatively large and there are more decimal places retained.

Although the accuracy of 15 bits is poor, it is calculated (1 to 3) * 3 to 1.

The maximum and minimum integer values are:

-79228162514264337593543950335-79228162514264337593543950335

There are more than one trillion yuan in Beijing.

Because ([System.Math]:: Sqrt (792281625264337593543950335)) = 281 4749 7671 0656, that is, 15 bits.

Calculate 14-bit decimal 9, multiplied by 14-bit decimal 9, that is, this program should be a 14-bit calculator.

[advanced usage]

This procedure is to call the. Net library to complete the operation.

This program is a simple formula calculator in theory.

You can calculate a negative number: 3-5-20

In the formula bar, enter:

[System.Math]: Sqrt (2) can calculate the square root of 2.

[keypad input]

First place the cursor over the formula input field and make sure the [numlock] light is on.

Keypad enter key = calculation result

Esc key = return to zero
