### Shifted Function Mathematical Operations

- [Shift][EEX] Keys in numbers with explicit powers of 10.
- [Shift][SIN] Calculates sine.
- [Shift][COS] Calculates cosine.
- [Shift][TAN] Calculates tangent.
- [Shift][LN] Natural log.
- [Shift][ex] Calculates natural exponent to the power of x.
- [Shift][x2] Returns square of x.
- [Shift][sqrt] Calculates square root.
- [Shift][RAND] Executes the Random function. Returns a random number in the range 0 < x <1.
- [Shift][ ! ] Calculates factorial of x(where 0 ≤ x≤ 253).
- [Shift][yx] Returns y to the xpower.
- [Shift][1/x] Reciprocal.
- [Shift][RND] Rounds x internally to the number specified by the display format. Default is two digits to the right of the decimal point.
