My requirement is to import data from Excel which has both integer and floating point numbers. For example, 1 and 2.5 I want to differentiate between them. But the Excel import coverts all numeric data into 'double' which is floating point by default.

Any help in this regard is appreciated! Thanks!

What makes you think 1 is stored as an integer? It might very well be a double.

在 MATLAB Online 中打开

is_integer = your_data == floor(your_data);

isinteger(floor(2.3)) also returns a 0. So how is it possible to differentiate integers from floating point numbers then?

Oh yeah now I get it if (my_data==floor(my_data)) 'Its an integer' else 'Its a floating point value' end This works well! Thanks for the help!
