### Printing decimal numbers, but not zeros

Hi!

I'm working on a little hobby project outside of my C++ class where I'm trying to experiment with some ideas we haven't used in class (So it's not homework just to clarify).

I'm basically writing an Ohm's law calculator which prompts the user for the first variable type, and then get the input for that variable. Then it will get the second variable and depending on what kind of variable it is, it will run some logic to use the correct equations.

My code is working as I want it to (as far as I have written it at least), but what I want to do is make some condition where if the value is a "nice" number (as in say just 2, or 30, a "not nice" number would be something like 2.351).

Lets say for instance we have this in my console:

 ``1234567891011`` ``````Enter the first known variable (V, I, R, P): I Enter the current: 0.07186 Enter the second known variable (V, R, P): P Enter the power: 0.2 Power / Current = Voltage 200.000mW / 71.860mA = 2.783 V Power / Current^2 = Resistance 200.000mW / 71.860^2 mA = 38.731 Ohms ``````

I want to make it basically so values like 200.000mW print out only as 200mW, or 71.860 will print out as just 71.86mA.

 ``12`` ``````setf.precision(3); cout.setf(ios::fixed);``````
