Algorithm (Workflow)

This function, isodd, determines whether a given number x is odd.

Input Parameters

x: A number that you want to check for oddness.

Output Results

r: A boolean value that is true if the number x is odd, and false if it is even.

Algorithm Explanation

The function uses the modulus operation to determine if a number is odd. The modulus operation mod(x,2) calculates the remainder when x is divided by 2.

If mod(x,2) ~= 0, it means the remainder is not zero, indicating that x is odd, and the function returns true.
If mod(x,2) == 0, it means the remainder is zero, indicating that x is even, and the function returns false.

Additional Information

This function is part of the SolidGeometry library and was introduced in version 1.0. It is categorized under auxiliary procedures and was created by Tim C. Lueth.

Related functions include isinteger and isintegerbv, which may be used for checking integer properties.
