This Engineering calculator offers super-precise calculations, goniometric and logarithmic functions, matrix and statistical functions, complex numbers, unit, hexadecimal and binary number conversions, Fourier transformations, as well as algebraic solutions of derivatives and equations.


Examples of operators, functions and constants:

+ | - | * | / | ^ | ! | & | mod | sqrt() | log() | sin() | cos() | tan() | cot() | asin() | acos() | atan() | asinh() | acosh() | atanh() | acot() | e | pi | phi | 0x7FF | 0b1011101

This Engineering calculator is also available as a palette directly inside AutoCAD and AutoCAD LT - see MathCalc in the Download section.

This free online calculator is based on the libaries Decimal.js (for BigNumbers) and Math.js.
