I am using this formula in my code.
z = (6.112*pow(2.71828,(17.67*x/(x+243.5)))*y*2.1674)/(273.15+x);
with values x=20.88 and y=88 (all are floats)
I get z=15.7
However, if I plug in the same values in an excel spreadsheet
I get 16.006
Difference is almost 2%. Why the difference?
Any help appreciated
