You type in an arithmetic expression, and it returns the value of that expression. The calculator works with both base 10 and base 16 numbers. Operations are performed from left to right on a priority basis. Parentheses may be used freely to force operations to be done in a specific order. DEG is probably more useful, since trigonometric functions expect their arguments to be in radians.
All trigonometric functions work with radians.
You must give at least two values to the MAX and MIN functions. Parentheses may be nested twenty deep. The range of valid numbers is from 10 to 10 . Their original value is 0.0 when you enter the program.
