FXCalc Scientific Calculator

FXCalc is an accurate formula scientific calculator with a modern look.

Enter a mathematical expression and use the equals button to evaluate it, carrying out calculations in sequence determined by common mathematics order of operations.

Note: The In-App purchase permission is for buying advanced optional features in the future, to support development of this app. The current features and some of the future features will always remain free.

The expressions and their results are stored in the calculation history. To go back and forward in history, use the up and down arrow buttons.

To start editing the displayed formula, use the left or right arrow button. When editing a formula, use these buttons or tap anywhere within the formula to move the caret.

To clear the current formula, use the AC button. When viewing a formula, you can also just start entering a new expression without clearing the old one.

To switch between the insert and replace modes, use the INS toggle button.

The calculation results can be displayed in different formats.

To display results in normal (fixed point) notation, use either Nor1, Nor2, or Fix buttons.

To display results in scientific (exponential) notation, use either Sci or Eng buttons.

To adjust the number of digits to display, long-press the button (except Nor2) then use the slider.

The angles (e.g. for trigonometric functions) can be expressed in either Degrees, Radians or Grads. To cycle between angle units, use the DRG button.

To access the hyperbolic and inverse trigonometric functions, use the hyp and inv toggle buttons.

Currently, two variables are available to use, additional variables will be added later.

The answer variable (Ans) is a special variable that contains the result of the last successful calculation. To recall it's value, use the Ans button.

The memory variable (M) is a general purpose variable with dedicated buttons

To set, recall and clear (set to zero) the memory variable, use the MS, MR and MC buttons.

To increase or decrease the value of the memory variable by the current value, use the M+ and M- buttons.

The display precision is limited to at most 12 decimal digits, the decimal exponent range is limited to [-99; 99].

Internally, the calculator uses IEEE 754 double precision floating point arithmetic, allowing representation of numbers with a decimal exponent range of [-308; 308] with 15–17 decimal digits precision.

FXCalc是一个准确的公式的科学计算器与现代的外观。

输入一个数学表达式，并使用等号按钮对其进行评估，开展业务所常见的数学顺序决定顺序计算。

注意：在应用程序内购买权限是购买先进的可选特性在未来，以支持这个应用程序的开发。目前的功能和一些未来的功能将始终保持自由。

的表达和其结果存储在计算历史。回去历史前进，使用向上和向下箭头按钮。

要开始编辑公式显示，使用向左或向右箭头按钮。当编辑公式，使用这些按钮或公式内的任何地方挖掘移动插入符。

要清除当前的公式，使用AC按钮。当查看公式，也可以刚开始进入一个新的表达不清除旧的。

要插入之间切换替代模式，可以使用INS切换按钮。

计算结果可以显示在不同的格式。

要显示正常（定点）符号的效果，请使用NOR1，NOR2或修复按钮。

要显示科技（指数）符号的效果，请使用SCI或工程按钮。

要调整的数字显示，长按按钮（NOR2除外）的数量，然后使用滑块。

该角度（例如三角函数），可在任一度，弧度或梯度来表示。要角度单元之间循环，使用DRG按钮。

要访问双曲和反三角函数，使用HYP和INV切换按钮。

目前，两个变量是可用的使用，附加变量将在后面加入。

答案变量（ANS）是包含上一次成功计算的结果的特殊变量。要调用它的价值，使用应答按钮。

存储器变量（M）是具有专用按钮的通用可变

要设置，调用和清除（设置为0）的内存变量，使用MS，MR和MC按钮。

要增加或电流值减少内存变量的值，可以使用M +和M-按钮。

显示精度被限制在至多12个十进制数字的十进制指数范围限制为[-99; 99]。

在内部，计算器使用IEEE 754双精度浮点运算，让数字的表示与[-308十进制指数范围; 308] 15-17与十进制数字精度。
