- Automatically use the last result as the first operand if an operator is the first input in normal mode. For example, after calc an expression, 2+3, we get 5 as the result. Now the expression box is empty and user press a + button directly, the last result 5 will be added as the first operand and the expression looks like: 5+. If there is no last result, 0.0 will be added.
- Minus sign is supported. Now user can press - to add a minus sign before an operand. The following expression is supported now: -5+3 In order to add the last result for -, user need to long press the – button.
- The default n-th of a root operator is a Square root. In the earlier version, the n-th of a root operator can not be omitted. It must be written as x√y. Now if the n-th (x) is absent, the operator will be recognized as a Square root operator. It is easier for some common usage.
In some scenarios, you need to do a serial calculations that only the numbers are changed, but you have to input the whole expression again and again.
You need a calc supporting variables which represent the numbers, so every time, you only need to input the numbers. You needn't to remember the formulas any more.
DaCalc is such a formula calculator. It supports composing a new formula, loading, editing, importing and exporting.
