-    Convert a float parameter to an integer, based on a total length.

-    Parameters
-    ----------
-    parameter : int or float
-        The parameter to convert. If float, it should be between 0 and 1.
-        If int, it should be non-negative. If -1, it will be replaced with total_length.

-        The total length to calculate the parameter from if it's a fraction.

-    -------
-    int
-        The calculated parameter.
