MPH couts 1.#INF -- not sure why... even if I use setprecision. Any ideas?Code:{ float MPH, hours; int Miles; Miles = 37 + ((15000/5280) + (12000/YARDS_IN_MILES)); hours = 45/60; MPH = Miles/hours; cout << "MPH: " << MPH; return MPH; }
MPH couts 1.#INF -- not sure why... even if I use setprecision. Any ideas?Code:{ float MPH, hours; int Miles; Miles = 37 + ((15000/5280) + (12000/YARDS_IN_MILES)); hours = 45/60; MPH = Miles/hours; cout << "MPH: " << MPH; return MPH; }
Well: hours is set to 0.0 (since 45/60 is 0 remainder 45, and remainder don't count); and dividing by 0.0 gives 1.#INF, since the fancy infinity sign is hard to print.
In other words: do hours = 45.0/60.0; instead.
The result of this expression - dividing an integer 45 by an integer 60 yields zero. Then, you divide Miles by zero.

And as a metric user, I have no idea what YARDS_IN_MILES is, but if it's a integer, too, there's another bad calculation.
