age_in_years
The current age of the agent in years, including fractional parts of the year.
Synopsis
age_in_years
Description
This factor evaluates to an approximation of the number of years since the agent’s
assigned birthday, using the formula age_in_days / 365.25.
The result is a real number; that is, if age_in_days is 1500 then
age_in_years evaluates to 4.106776. To get the number of whole years, use
age.
This calcuation of age_in_days is exact for agents born during the
simulation period. For agents with birthday’s prior to the simulation
start_date, the calculation of age_in_days assumes 365.25 days
per year; that is, it may not be accurate due to leap days.
Examples
Suppose an agent is \(1500\) days old, as determined by age_in_days.
In this case, age_in_years evaluates to 4.106776.
