It's nice to remember those wonderful times when, as children, we didn't have to count anything outside of the school mathematics course. Now you have to count everything and constantly. Few of us are engaged in budget planning, making do with just a pen and a piece of paper. And if you find a sensible multifunctional calculator, then you can find a place for it not only in the financial component of life.
The standard Android calculator is not very fancy and particularly convenient to use, and in order not to waste time searching for a suitable sane alternative in the Google Play Store, we advise you to try in practice a free calculator called Easy Calculator Pro.
This calculator is very versatile and suitable for any purpose. The main button panel is no different from the usual calculators. In order to fit more operations into the minimum set of buttons, leaving them as large as possible for the convenience of pressing, some additional button values are called by long pressing on them. It is worth noting that Easy Calculator Pro counts everything in the process of entering an expression. In other words, the user does not need to press "=" to get the result. As you enter numbers and operations, the answer is displayed in real time.
It is very important that all operations are recorded in the calculation log, which allows you to return to previously performed calculations. For each log entry, you can add a comment, or use it for further calculations. Those who use multistage calculations with entering the results into memory will like the fact that this calculator has an unlimited number of memory cells.
Like any mass-market product, this calculator is equipped with an additional panel of buttons that turns it into an engineering calculator. Despite the fact that these options are in demand by a rather narrow circle of people, whether they are students of technical specialties and other mathematicians of this world, there are also several additional features that can be useful to anyone in everyday life.
For example, Easy Calculator Pro is able to work with percentages in a smart way. Need to calculate the percentage of a complex expression in one action? It is enough to assign the desired percentage at the end of the expression.
Often there is a need to perform multiple calculations involving the same number. The calculator allows you to remember a certain number and even part of the expression in the form of a template, which is then called by pressing a single key. For example, we count some amounts with VAT. Enter the expression 1.18* and press the C (set) key. Now when you press C, the remembered expression is automatically inserted. To return the C key to its original destination, you just need to "remember" an empty input field.
In order for the user to spend less time switching between a simple and an extended button panel, the calculator has a "smart button" located in the upper left corner and allows you to access some additional functions directly from the current keyboard.
Another very useful function is working with dates and time periods. Do you need to quickly count the number of days between two dates or find out the date following the nth number of days after the given one? Easy.
If a syntax error occurs in the expression, the calculator does not go into Error, but reports incorrect input. In this case, the entire syntax of the expression is highlighted in a different text color.
In order to quickly go to the part of the expression that needs to be corrected, a cursor is provided here. This is much more convenient than trying to get to the right part of the expression by aiming micro-steps on the screen.
For even more convenient work, there is a clipboard here. You just need to tap and hold your finger on the desired area, after which the appropriate interface will appear.
It is often necessary that the result of calculations be presented in one or another specific form. Here it can be done by simply holding your finger on the result.
In the menu that appears, there is a "View" option that allows you to specify the display format.
The calculator also perfectly supports working with angles in the degrees-minutes-seconds format. The function for entering angles in this format is located on an additional keyboard, but for quick access it is easily hung on a smart button, and the result can also be displayed in the desired form through a long tap on it.
In addition, the calculator has a lot of constants, which greatly simplifies the input of the necessary expressions with their use, and the configurable accuracy of up to 40 significant characters will be sufficient for the absolute majority of users.
For a full acquaintance with all the features of the calculator, you can call the built-in help, which describes all the nuances of using this tool.
