Inverse on exchange

[BrielC]

From my side as well. Its really a great module to have. My country's currency is weaker than the USD and GBP ext. The exchange make better more sense if we see the inverse. This is the way we hear it on radio and the way we understand it. Would it be possible to bring in an inverse option on the answer.

New Answer = 1 / Answer

Currently what i will see on the exchange is GBP = 0.0563 USD = 0.0705

But what i would really love to see is GBP = 17.75 USD = 14.18

This is the cost for me to purchase a USD or GBP Or basically as below:

base: 'GBP', symbol: 'ZAR', base: 'USD', symbol: 'ZAR'

I just did this change to have this functionality. I am not that good in programming js, but I learn slowly ` index 556e1f8..58af87a 100644 --- a/MMM-CurrencyExchange.js +++ b/MMM-CurrencyExchange.js @@ -126,7 +126,8 @@ Module.register('MMM-CurrencyExchange',{ }

                    var rateSpan = document.createElement('span');

• rateSpan.innerHTML = ((this.config.layoutStyle == 'ticker' && i < (this.rates.length - 1)) ? this.rates[i].rate + ' • ' : this.rates[i].rate);
• MyNum = 1 / this.rates[i].rate;

• rateSpan.innerHTML = ((this.config.layoutStyle == 'ticker' && i < (this.rates.length - 1)) ? MyNum.toFixed(2) + ' • ' : MyNum.toFixed(2)); rateContainer.appendChild(rateSpan);

Hi Mikael Thanks very much for taking the time to help. I am going to try this over the weekend. Its really much appreciated and i will let you know if it worked Best regards Cobus Briel

A more cleaner solution: Add to config.js a new line with inverseRate: true :

  layoutStyle: 'table',
  inverseRate: true,
  initialLoadDelay: 0, // 0 seconds delay
  apiBase: "https://api.exchangeratesapi.io/latest",

In MMM-CurrencyExchange change to the following around line 128 from:

          rateSpan.innerHTML = ((this.config.layoutStyle == 'ticker' && i < (this.rates.length - 1)) ? 1 / this.rates[i].rate + ' &bull; ' : 1 / this.rates[i].rate);
      rateContainer.appendChild(rateSpan);

to:

      if (this.config.inverseRate) {
          inversedrate = 1 / this.rates[i].rate; // Inverse the rate
          rateSpan.innerHTML = ((this.config.layoutStyle == 'ticker' && i < (this.rates.length - 1)) ? inversedrate.toFixed(2) + ' &bull; ' : inversedrate.toFixed(2));
      } else {
          rateSpan.innerHTML = ((this.config.layoutStyle == 'ticker' && i < (this.rates.length - 1)) ? 1 / this.rates[i].rate + ' &bull; ' : 1 / this.rates[i].rate);
      }
      rateContainer.appendChild(rateSpan);

@mickecamino Thanks for your solution. I am mostly offline currently, but received a mail notification about your response. Would you mind if I integrate this into the module?

[mickecamino]

@yawnsde Please do integrate it. I decided to use only two decimals in the inversed rate, it should perhaps be a setting in the config.js? Thanks for a great module.

[BrielC]

The module is working now exactly the way i wanted it to. Thanks very much once again for the help and effort. Great start to my weekend :-)

Please help me figure it out. I want to see how much the dollar and the euro are worth in rubles.

config: { base: 'USD', symbols: ['RUB'] }

Meets my expectations, but:

• I want to see the dollar symbol, not the ruble as it is now
• I cannot add euro

config: { base: 'RUB', symbols: ['USD', 'EUR'] }

In this case, I see how much 1 ruble costs. As far as I understood from the discussions, adding inverseRate: true should show me how many rubles are 1 dollar and 1 euro, but this does not happen.

[BrielC]

Hi nafanz

There is more code to change than only inverseRate: true

If you give me an email address then i will mail you my *.js file with all the changes. The only additions that i made was to increase the font
