# Scientific Calculator

## What is a scientific calculator?

Basically a scientific calculator is nothing but a type of the electronic calculator which has been designed specifically keeping in mind the calculations related to not only mathematics but also engineering & science. These calculators have also to a great extent replaced the slide rules in the traditional applications.

## Functions of scientific calculators

The modern functions of a scientific calculator include the following – scientific notation, logarithmic functions using base 10 as well as base e, floating point arithmetic, exponential functions & the roots beyond the square root, trigonometric functions (includes hyperbolic trigonometry), quick access to pi & e constants.

The high – end scientific calculators come with the below given aspects – complex numbers, cursor controls to edit the equations & view the previous calculations, fractions calculations, hexadecimal, binary & the octal calculations & this includes the Boolean math, programmability, statistics & probability calculations, calculus, equation solving, conversion of the units, matrix calculations, physical constants, letters which can be made use of when spellings words or even including variables in an equation.
