Find difference between two numbers (DBL)

[Davidson_D]

Hello All,

Is there a function in labview other than subtraction function that can find the difference between the two given numbers?

Thanks,

Davidson

May be this.

Is that not still subtraction?

You could extract mantissa and exponent. Then implement the bit-arithmetics on your own.

Thanks for the replies..!!!

I tried a VI.

Please find the attached one and let me know if there is any case where it won't work. 🙂

Any suggestion on how to do this better is greatly appreciated!!!

Thanks,

Davidson

You yourself have used subtract function.

I think what you are after is the 'Absolute' Value:

This will return the difference as a positive value.

Hmmmmm...... Im not too sure if that is what you are after now after running your code???? What exactly are you on about?

Rgs,

I think if he wanted to find absolute value he would have mentioned it.

And not asked about other function for taking difference.

Do you want to fight over this? When it is mentioned "DIFFERENCE" and not "ABSOLUTE" value.

Anyways..Will fight tomorrow. I am going home.

Best of luck

Ok.. 😉 I'll break it down 😉

I expect the difference between two numbers with sign.

In the VI snap, what will be the output for Numeric= (-1) and Numeric2 = (-5)

The output i expect is (-4).

I was thinking of labview function which can give me the exact difference;-)..

Thanks,

Davidson
