Scientific Calculator

This is a very powerful Scientific Calculator
You can use it like a normal calculator, or you can type formulas like (3+7^2)*2
It has many functions you can type in (see below)

Examples

  • Type in 12+2*3 (=18)
  • Select "deg", type in cos(45) (=0.7071067811865476)
  • Type in 2/sqrt(2) (=1.414213562373095)

Function Reference

A function will return NaN (Not a Number) when you give it invalid entries, such as sqrt(-1)

Operators

  + Addition operator
  - Subtraction operator
  * Multiplication operator

  sinh Hyperbolic inverse sine (arcsine) of a value or expression
  cosh Hyperbolic inverse cosine (arccos) of a value or expression
  tanh Hyperbolic inverse tangent (arctangent) of a value or expression
  exp e (the Euler Constant) raised to the power of a value or expression
  ln The natural logarithm of a value or expression
  log The base-10 logarithm of a value or expression
  abs Absolute value (distance from zero) of a value or expression
  deg convert radians to degrees
  rad convert degrees to radians
  sign −1 for values less than 0, otherwise 1
  round round to nearest integer
  floor Returns the largest (closest to positive infinity) value that is not greater than the argument and is equal to a mathematical integer.
  ceil Returns the smallest (closest to negative infinity) value that is not less than the argument and is equal to a mathematical integer.
  fact factorial function

Constants

  pi The constant π (3.141592654...)
  e Euler's Number (2.71828...), the base for the natural logarithm
