Leonhard Euler is the king of mathematics, even he was blind !Euler introduced much of the mathematical notation in use today, such as the notation f(x) to describe a function and the modern notation for the trigonometric functions. He was the first to use the letter e for the base of the natural logarithm, now also known as Euler's number. The use of the Greek letter π to denote the ratio of a circle's circumference to its diameter was also popularized by Euler (although it did not originate with him).[1] He is also credited for inventing the notation i to denote .[2]I salute him.

28.6 is the standard notation. The standard form(also called scientific notation) is: 2.86 × 101
4.73x102 is 473 in exponential notation. This can also be written 4.73E2 or 2.73e2
5.400000e-7Scientific notation is also know as exponential notation. Numbers in scientific notation must be entered in E notation. For example, 1.23 x 10^7 is entered as 1.23E7 or 1.23e7.
