At the end of his life, he was devoted more and more to numerical calculation.

Before word processors became common, many people thought of computers as dealing entirely with numerical calculation.

He early showed great liking for, and aptitude in, numerical calculation.

Before computers were used, numerical calculations were done by hand.

Estimators that do not require numerical calculation have also been proposed.

In some they will be quite simple numerical calculations, for example:

In the first decades of the 20th century, numerical calculations were based on decimal numbers.

Predictably, they are not well suited for general purpose numerical calculations.

These relationships are often established empirically, and one refers to them for numerical calculation.

In this work, the Green's function method formed the basis for numerical calculations.
