Frequently Asked Questions
Which functions are supported? expand_more
Trigonometry (sin, cos, tan, asin, acos, atan), logarithms (log base 10, ln), powers (^), square root (sqrt), absolute value (abs), exp, and the constant pi.
Are angles in degrees or radians? expand_more
Radians. To convert degrees to radians, multiply by pi/180. To use 90 degrees, type sin(pi/2).
How does the parser handle order of operations? expand_more
It uses the shunting-yard algorithm to convert your expression to Reverse Polish Notation, then evaluates with correct precedence and associativity.
Need bitwise operations? expand_more
Use the [Bitwise Calculator](/tools/bitwise-calculator/) for AND, OR, XOR, and shifts.
Is my input uploaded? expand_more
No. Everything runs locally in your browser.
