recalculates

Recalculates is the third-person singular present tense of recalculate, meaning to compute something again or update previously computed results after input data have changed. In computing and data processing, recalculation is the process of re-evaluating a set of expressions, formulas, or models to reflect new information. Recalculation can be triggered automatically by a change in inputs or initiated explicitly by a user or program.

In spreadsheet software, recalculation is a fundamental operation. Cells containing formulas are reevaluated when their dependent cells change, and software typically offers automatic or manual recalculation modes. The performance of recalculation depends on the size of the workbook and the complexity of dependencies; many systems support incremental or partial recalculation to avoid redoing work for unaffected parts.

In programming, data analysis, and simulations, recalculation occurs whenever inputs or parameters are updated. This can involve re-solving equations, re-running simulations, or invalidating cached results and recomputing outputs. Reactive programming and dataflow systems rely on automatic recalculation as changes propagate through dependency graphs.

Potential issues during recalculation include circular references, which can prevent stable results; convergence problems in iterative methods; and floating-point rounding errors that affect numerical accuracy. Efficient recalculation often requires careful design of dependencies, caching, and update strategies to balance correctness with performance.
