Evaluate a maths expression following the standard order of operations (BODMAS). Supports + - * / ^ (power), ! (factorial), % (as divide by 100), brackets, the constants pi and e, and the functions sin, cos, tan, asin, acos, atan, ln, log (base 10) and sqrt. Set angleMode to 'deg' (default) or 'rad' for trigonometry. Source: https://hopi.co.uk/scientific-calculator/
