Esta é a versão Javascript da nossa calculadora financeira em Java. O funcionamento dos registradores financeiros assemelha-se à mítica calculadora financeira HP-12C, inclusive no arredondamento de "n". Os campos amarelos servem como parcelas das operações básicas; o campo azul conterá o resultado.
This is the Javascript version of our Java financial calculator. The financial registers at left work mostly the same as in a HP-12C calculator, even regarding the "n" rounding. Each financial register matches the button at its right. For example, fill the PMT register if you know value of payment, or fill the other registers and press PMT if you want to calculate PMT. The yellow registers are also used to feed the other arithmetic operations, whose results will appear at the blue register.
BEGIN: Se habilitado, considera que o primeiro pagamento é feito antecipadamente, em cálculos com PMT.
BEGIN: If enabled, the first payment is made at the beginning of the period. Matches the "begin" flag in HP-12C. It is important for calculations that involve non-zero PMTs.
CFP: Se habilitado, calcula juros compostos também para a parte fracionária de "n", se for o caso.
CFP: If enabled, the fractional part of "n" will be calculated as compound interest (more fair but not often used).
