Precise Calculator2.6

To help with math calculations at school or at work, you can resort to Precise Calculator, a lightweight Windows application that has arbitrary precision and gives you the possibility to determine mathematical equations using complex numbers, vectors, fractions, and matrices. It also supports logical functions used in programming, such as if..then, goto, return, and print.

Doesn't need installation

Installing this tool isn't necessary, since it's wrapped in a portable package that can be placed anywhere on the computer or stored on a thumb drive to seamlessly launch Precise Calculator on any machine and start making calculations. It has no software requirements.

Input text and edit expressions

As far as the GUI is concerned, the scientific calculator adopts a simple and plain look. It has a neatly structured main window, where you can use the keyboard to write complex equations as text.There's also a built-in calculator with functions for sine, cosing, tangent, absolute, pi, brackets, power, fraction, and, or, logarithm, natural logarithm, and others. Units can be displayed as degrees, radians or gradians, as well as decimal, hexadecimal or binary mode.

Insert constants and measurement units

More options can be accessed from the menu bar. For example, you can explore the constants menu to insert the speed of light, gravitational force, permitivity of vacuum, atomic mass, nuclear magneton, and other values. Units can be added to the calculator too when it comes to length, area, volume, mass, energy, power, pressure, time, and speed.Quadratic and cubic equations are supported, along with divisors and prime numbers. Furthermore, you can calculate plane (e.g. circle, square, rectangle), solid (e.g. cuboid, triangular prism, cylinder, cone) and statistics (standard deviation, standard deviation with frequency list, correlation, t-test).

Save macros and settings

It's also possible to save macros and settings to file to open them later and pick up where you left off. The colors can be customized.The program has help documentation but, unfortunately, it failed in its attempt to download it in our tests and display the syntax, operator precedence, function reference, computation time, and examples.

Multifunctional calculator for scientific operations

All things considered, Precise Calculator may not has a particularly appealing interface, but it comes packed with a wide range of advanced operators and functions to perform all kinds of calculations.
