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. In order to entering a value into a memory register, first enter the value, press [ENTER], then enter the register number and press [STO].
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.
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
