thiagofg · Julho 11, 2011, 12:08pm

Preciso de ajudas em uma calculadora, a desenvolvi toda no netbeans e consegui configurar as opções basicas tipo: “±/*”, mas existem algumas coisas que não consegui como potencia de 2, raiz quadrada, e também queria uma função tipo rolinho de papel igual as de mesa e a função de impressão se alguem puder me ajudar com os código java desde ja obrigado pois estou iniciando em java ainda!

No seu código, digite:


Math.

e vão abrir todos métodos ligados matemática

pow é a potência, sqr é a raiz

mas ali tem muitas outras: seno, coseno, tangente e tudo o mais que vc precisar.

[quote]Seu Código não, digite:

planície vista cópia para clipboard print ?

Matemática.

e Vão Abrir Todos MÉTODOS Ligados Matemática pow e uma Potencia, sqr e uma Raiz Mas ali temperatura muitas Outras: seno, coseno, Tangente e Tudo o Mais Que vc precisar.
[/quote]

Já tentei utilizar deste método mais não consigo encaixar com as variaveis do Visor e visor que tenho ali, tipo para fazer os calculos de potencia e raiz.

JoaoBluSCBR · Julho 11, 2011, 1:45pm

Vc tá de brincandeira, não?

Por que vc fez tudo isso que colocou no post e não consegue adaptar uma função de uma biblioteca???

teu código é sempre assim:

else if (operacao.equals("divisao")){   
    visor = visor / Double.parseDouble(Visor.getText().replace("," , "."));

vai fazer quase a mesma coisa. Elevar um número ao quadrado, ou tirar a raiz dele, é apenas fazer uma operação com o número que tá no Visor, entao:


else if (operacao.equals("quadrado")){   
    visor = Math.pow(Double.parseDouble(Visor.getText().replace("," , ".")),2);

ou se for a raiz quadrada será algo como:

visor = Math.sqr(Double.parseDouble(Visor.getText().replace("," , ".")));

thiagofg · Julho 11, 2011, 2:55pm

Obrigado, problema resolvido, na área de potencia e raiz, mais ainda não consigo fazer com que os valor subão para cima assim como naquelas calculadoras de papel fazendo fikar tipo assim:

200,00 +
330,00 -
100,00 *
50,00 /
= 1060,00

se alguem puder ajudar

JoaoBluSCBR · Julho 11, 2011, 3:22pm

Cara, vou tentar te responder mas vou postar no outro tópico que vc abriu.

Este aqui tá uma merda por causa do tamanho do código que você postou no
inicio. Toda vez que vc clica em responder ele relê aquele código todo e
demora muito para disponibilizar essa telinha de resposta.
