Fractional assumptions are:

linear: linear interpolation between consecutive ages, i.e. assume uniform distribution.

constant force of mortality : constant force of mortality, also known as exponential interpolation.

hyperbolic: Balducci assumption, also known as harmonic interpolation.

Function `dxt`

accepts also fractional value of t. Linear interpolation is used in such case. These functions are called by many other functions.
