HP12C EMULATOR

Esta calculadora é apenas um simulador. Use por sua conta e risco! Ela responde a algumas teclas (além do mouse) o que torna mais fácil o seu uso:

Números, ponto/vírgula decimal e sinais aritméticos de planilha (+,-,*,/)

Enter/Return ou sinal de igual = ENTER

C = CLx (Clear x, zera visor)

H = CHS (muda o sinal)

E = EEX

Teclas modificadoras: (F, G, S, R) equivalem a (f, g, STO, RCL)

Teclas Financeiras: (N, I, P, M, V) equivalem a (n, i, PV, PMT and FV)

Percentagem: (#, $, %) equivalem a (T%, delta% e %)

! = potenciação (y**x)

\ = recíproco (1/x)

X = troca x com y (x<->y)

D = R-down (roda a pilha para baixo)

W = Tecla sigma-plus (adiciona amostra estatística)

O = Liga/desliga (muda entre ponto e vírgula decimal)

[ = R/S

] = SST

? = Mostra detalhes das memórias (serve para depuração ou curiosidade)

Backspace = Apagar último dígito (apenas no Firefox)

This calculator is only a toy. Use it at your own risk! There are some key bindings that make the emulator easier to use in typical usage:

Numbers, decimal point/comma and arithmetic (+,-,*,/)

Enter/Return or Equal sign = ENTER

C = CLx (Clear x)

H = CHS (change signal)

E = EEX

Modifiers: (F, G, S, R) map to (f, g, STO, RCL) modifiers

Financial: (N, I, P, M, V) map to (n, i, PV, PMT and FV) operations.

Percentage: (#, $, %) map to (T%, delta% and %)

! = power (y**x)

\ = inverse (1/x)

X = swap x with y (x<->y)

D = Rotate down stack (R-down)

W = Add statistical tuple (sigma-plus key)

O = On/Off key (toogles between decimal point and comma, and also saves memory as a cookie)

[ = R/S key

] = SST key

? = show memory dump (ugly HTML, mostly for debugging or plain curiosity)

Backspace = correct typing (Firefox only)

If you prefer a simpler calculator (with the basic financial and arithmetic operations) or if you don't know the RPN notation, you can try this form-based calculator instead.
