Calculator

andanCalc PRO is a versatile Chrome extension combining two calculators in one. Use the Standard Calculator for everyday tasks with classic desk functions like square roots, memory, and diverse percent calculations including mark-up and mark-down. Switch to the Scientific/Algebraic/Fraction Calculator for more complex needs such as exponents, logarithms, trigonometry functions, fractions, and statistical calculations.

This extension supports conversions between fractions and decimals, improper fractions and mixed numbers, as well as DMS to decimal degree and polar to rectangular coordinate conversions. Additional features include random number generation, factorials, scientific notation, and multi-window support on compatible Samsung devices. Customize your experience with portrait or landscape layouts, dark mode, and a clipboard copy function. Perfect for office, school, and scientific studies, and mimics classic calculator models like the fx 82 and fx 260.
