What is the Scientific Calculator?
This scientific calculator evaluates a typed mathematical expression using a restricted syntax: numbers, arithmetic operators, parentheses, constants pi and e, and a fixed set of functions (trigonometric, logarithmic, etc.). It does not execute Python or JavaScript code.
Why people use this calculator
Quick checks for homework, engineering estimates and hobby projects without installing software. The restricted parser reduces security risks compared to generic eval.
