How to add final iteration to while loop?

I have a function that runs a while loop:

void run_while_loop(const float x_d, const float x_max) 
{
    float x = 0;
    while ( x < x_max ){
        // do something
        x += x_d;
    }
}

It is assumed that x_d < x_max.

I want to change the function so that it adds an iteration at the end with x = x_max. If the function were called as:

run_while_loop(1, 3.123)

then I want the while loop to iterate for x = 0, 1, 2, 3, and 3.123.

What is an elegant way to code this? Thank you very much.

Wrap the code that is inside the while loop into a function, and call that function after the while-loop.

void run_while_loop(const float x_d, const float x_max) 
{
    float x = 0;
    while ( x < x_max ){
        do_something_function(parameters...);
        x += x_d;
    }
    do_something_function(final_parameters...);
}
