Number 'e'
2.7182818284590452353602874713526624977572
The transcendental number 'e' is the sum of the infinite series:  is used extensively in science and mathematics particularly calculus and natural logarithms. Natural logarithms also known as Naperian logarithms have a base equal to 'e' or 2.718281828459. ************************************************************************************************************ The constant 'e' appears quite often in mathematics. When calculating compounded interest we use the formula: Total = principal*(1 + rate)^years For $1,000 invested for 2 years at 10 per cent interest compounded yearly yields: $1,000 * (1.10)^2 = $1,210.00
However, to get the value for continuously compounded interest we use the number 'e': Click here for a continuously compounded interest calculator
