English term or phrase: In, exp
In, exp +, -, x and / functions enable derived engineering units to be displayed, recorded and transmitted to data acquisition systems.

What is *exp* in this context?? Please help!

Selected answer:[NFG] natural logarithm, exponential function
Explanation:
I have no desire to pinch the points; Mikhail had the right idea.

I am assuming the first is "ln" rather than "In". This forms a pair with "exp" in that the two functions are inverses of one another. So if you enter a number x, take the exponential of x (e^x or exp(x)) and then take the natural logarithm the result, you should get back (allowing for rounding error) the number x you started with, i.e. ln(exp(x))=x. Similarly, if x ispositive, exp(ln(x))=x (the logarithm of a negative number or zero is not defined in the real number system).

Cheers,
Richard.

exponent - x to y power


Explanation:
exp(x,y) = x^y = raised to y power

As Richard kindly states, it could just be e^x. That's very likely as well. You enter a number (x), press the EXP button, and the result is e^x.
With my explanation, you would need to enter a number (x), then press the button (usually reads "x^y"), THEN enter the second number (y) and the result is x^y.

  -> You are correct - that appears more likely, in fact! Didn't think about it!
