Recieving 0.0 when multiplying two doubles in an array. Any help? (noob issue)


You're only modifying the first element of speedMPH (n is always 0). I'd recommend using a normal for-loop, because you need the current index.

for (int i = 0; i < speedK.length;
i++) {
    speedMPH[i] = speedK[i] * 1.15078;
}

Casting to double is not necessary. If you really want to use an enhanced for-loop, you need to increment n:

int n = 0;
for(double speedTemp : speedK) {
    speedMPH[n] = speedTemp * 1.15078;
    n++;
}

Random Even Logarithmic Distribution Between Two Doubles
Is this what you want? I took numbers uniformly distributed over the range formed by the logs of the limits, then used Math.exp to convert back to the actual range. I sorted the result array because your examples showed sorted data. Delete the Arrays.sort call if you don't want that. For simplicity, I skipped the bounds checking. Presumably, 0 < lowerLimit < upperLimit. The checks for the

Calculating pow with doubles gives wrong results
You're just hitting rounding errors. There's nothing you can do about this, except revert to an integer-based approach whenever the inputs are integers. You could condition on whether the inputs are integers, and if so then use integer arithmetic; if not, then use doubles. But using exp and log will always introduce rounding errors, so you can't expect exact answers with that approach. More prec

How can I divide two doubles and output the quotient?
int quant = (int)(money / 0.55); if ( quant >= 1 ) printf( "You selected Mars and have enough money to buy %d bars", quant ); This will remove everything after the decimal point. If you want to force round up or down you need the functions floor and ceil

rspec-mocks' doubles are designed to only last for one example
surely this is an appropriate use of a double being used in 2 examples. No, it's not. :) You're trying to use a class variable; do not do that because the variable doesn't span examples. The solution is to set the client each time i.e. in each example. Bad: @client ||= Strava::Api::V3::Client.new(access_token: 'abc123') Good: @client = Strava::Api::V3::Client.new(access_token: 'abc123')
