Algorithm (Workflow)
This function, isintegerbv, determines whether elements in an input are integers by value, not by type. It was developed by Tim Lueth and is part of the SolidGeometry library.
Input Parameters
- x: This can be a scalar, array, or vector. It represents the input data for which the function will check if each element is an integer by value.
Output Results
- l: This is a logical value, array, or vector. It indicates whether each corresponding element in
x is an integer by value. The output is true if the element is an integer, and false otherwise.
Algorithm Explanation
The function uses the modulus operation to determine if a number is an integer by value. Specifically, it checks if the remainder of the division of each element in x by 1 is zero. If mod(x,1) == 0, the element is considered an integer by value.
Example
Consider the example call: isintegerTL([pi pi pi;2 4 5;1.4 3 2.4]). This will return a logical array indicating which elements are integers by value. In this case, only the elements 2, 4, and 5 will return true.
