Scientific calculators are set apart from standard calculators. It has so many functions and features not seen in standard devices. It is very useful to students and businessmen.
A scientific calculator is primarily used in solving problems in physics, engineering, math and science. It has special features that make computations much easier. Some of these are the floating point in arithmetic, functions in trigonometry, exponents and roots, scientific notation, and easy access to constants including E and pi.
The high end models have features of statistics and probability calculations, equation solving, programmability, fractions, complex numbers, and hexadecimal binary and octal calculations, which comprises of basic Boolean math.
Uses of Scientific Calculators
The uses of scientific calculators are best seen in various aspects and situations. It is time consuming to look for functions on a logarithmic table, as compared to scientific calculator which can readily access certain mathematical functions like the trigonometric functions in a speedy manner. The calculator is needed to calculate problems in Chemistry, Astronomy and Physics involving very large numbers.
Here are some of the common models in the market:
