What it understands

• Operators + - * / % (% is the remainder, so 7%4 is 3), powers with ^ or **, brackets, and × and ÷.
• Functions sqrt abs round floor ceil sin cos tan log ln exp min max pow, and the constants pi and e.

(2+3)*4          → 20
2^10             → 1024
sqrt(16)+max(1,2) → 6

Only complete, valid expressions are treated as maths. A bare number, a word, or something like 1/0 is left alone and searched normally.

History
