## Javascript RPN Scientific Calculator

This code was tested with Internet Explorer 4.0

I added three new functions over my previous
**scientific calculator**: LOG ,
10^X and Y^1/X .

This calculator has four memory registers. For entering a value into a memory register,
first enter the value, press [ENTER], then enter the register number and press [STO].

Example:

Save 15 in memory register number 2:

15 [ENTER] 2 [STO]

Suppose that in memory register 1 you saved the number 10.

1 [RCL] recalls 10 into X register.

Another example:

20 [ENTER] 3 [STO] You save 20 into memory register 3

15 [ENTER] 3 [STO+] Then, you add 15 to memory register number 3

12 [ENTER] 3 [STO-] then, you substract 12 from memory register 3

3 [RCL] then you recall the contents of memory register 3 (currently 23), and load this value into X.

[CLRG] means Clear All Memory Registers
