in #technology2 years ago

The calculator is meant to say the calculator . A small notebook type object that has a display unit. This display section shows the number of computation results or counters. Most of the calculators currently use digital and eca LCD screen. They have power or battery and very little. It can be seen that the watt is written behind the calculator, which is 0.004 or something more than that means that the cost of 1 percent of 1 watt of 1 watt is 4 percent of the current / ampea. That means 1/3 years to finish 1 good pencil battery.

Design
Modern electronic calculators have a keyboard with numbers for number and arnical operation. There are 00 and 000 buttons to make a lot of easier to write anything. Most basic calculators should be assigned only one address or operation on each button. However, more specific calculators, a button key combinations or work with the current accounting mode can perform multi function. The calculator usually has liquid crystal displays as the output of the historical vacuum fluorescent display places. See more technical improvements. For example, 1/3 fraction of decimal is displayed as approximations, such as round to do 033333333. In addition, such as 0.14285714285714 (14 significant figures) which can be difficult to recognize in some fraction decimal form as 1/7; as a result, Many scientific calculators can work in rude fractions or mixed numbers. Calculators also have the ability to hold numbers in memory. In it, only a number of basic types are stored at a time. More specific types of variables can be stored in represented numbers. Variables can also be used for formulas. Some models have the ability to extend the memory capacity to contain more numbers; Increased addresses are referred to as an array index. Calculator power source has electricity with a switch or button, solar cells or (for older model) power. Some models even have some close buttons on the port but they provide some way to stop, for example, covering a solar cell exposure, or closing their lid, leaving no operation for a moment.
