Supports all the functionalities of the HP12c Calculator including programming. Adds new financial functions (+).
Keyboard usage
The combination Alt+Q allows direct access to the calculator extension.
If it does not work automatically once installed, go to 'Extensions, Keyboard Shortcuts, Open the HP12c calculator' and use the Alt+Q combination.
It can be used in two sizes: 'large' or 'small'. Switch with f++ or f+−. The setting remains in memory for future uses.
All entered values will be retained in memory for future uses of the calculator.
There are some keys that make the emulator easier to use in typical operation:
Numbers, decimal point (comma or dot) and arithmetic operators (+, −, *, /)
Enter = ENTER
C = CLx (clear x)
Z or g − or = Corrects input (deletes the last digit)
H = CHS (change sign)
E = EEX (enter exponent)
Keys: (F, G, S, R) for (f, g, STO, RCL)
Keys for financial operations: (N, I, P, M, V) corresponding to (n, i, PV, PMT, FV)
Percentage: (%, $, #) for (%, %T, Δ%)
! = yx
\ = 1/x
Y = x<>y (exchange x and y)
D = Roll down the stack (R↓)
W = Add statistical value (∑+)
O = On/Off, toggle between decimal point (.) and comma (,) in European notation
[ = R/S (Run/Stop)
] = SST (Single Step)
New functions added
? or g + = Help. Access this page
f++ = Large size
f+− = Small size
g+/ = Keyboard key help
Ctrl-C or ⌘‑C = Copies the value from the display
Ctrl-V or ⌘‑V = Pastes the value from the clipboard
f+* = SAVEP = Allows saving a program to disk
f+/ = GETP = Allows loading a previously saved program from disk into the calculator
The number of CF/Nj has been increased to 30 as in the HP12c Platinum
The number of programming steps has been increased to 400 as in the HP12c Platinum
Decimal selection has been added and modified since new functions have been introduced with numbers. f+number of decimals is now f+(∑+)[or key W]+number of decimals, f+. still gives scientific notation.
f+1 = TAX− = Stores the base value in register 1, or calculates the TAX+ value minus TAX% tax: \( TAX- = \dfrac{TAX+}{\left(1 + \dfrac{TAX\%}{100} \right)} \)
f+2 = TAX% = Stores the tax percentage in register 2 or calculates the value between TAX+ and TAX− \(TAX\% = \left( \dfrac{TAX+}{TAX-} - 1 \right) \cdot 100 \)
f+3 = TAX+ = Stores the tax-included value in register 3 or calculates TAX+ by adding TAX% to TAX−: \( TAX+ = TAX- \left( 1 + \dfrac{TAX\%}{100} \right) \)
f+4 = NOM = Nominal interest rate. Stores the value in register 4 or calculates the nominal interest rate: \( NOM = \left[ \left( 1 + \dfrac{EFF}{100} \right)^{\tfrac{1}{\text{P/YR}}} - 1 \right] \cdot 100 \cdot \text{P/YR} \)
f+5 = EFF = Effective annual rate. Stores the value in register 5 or calculates the effective annual rate (EAR): \( EFF = \left[ \left( 1 + \dfrac{\dfrac{NOM}{100}}{\text{P/YR}} \right)^{\text{P/YR}} - 1 \right] \cdot 100 \)
f+6 = P/YR = Number of payments per year. Stores the value in register 6
f+7 = COST = Cost. Stores the value in register 7 or calculates the cost
f+8 = PRICE = Price. Stores the value in register 8 or calculates the price from the cost with the specified sales margin
f+9 = MARGIN = Margin in %. Stores the value in register 9 or calculates the sales margin corresponding to the specified cost and selling price
