type
  TFloat = Single;
  PFloat = ^TFloat;

Description

TFloat is a type alias for Single and is used in Graphics32 for historical reasons.

INFO

The original purpose of TFloat was to be able to switch between single- and double-precision by simply redeclaring TFloat as either Single or Double.
However, while this would work most of the time for pure Pascal code, it would in most cases require that all assembler code be duplicated with different versions for the two types.

Today, you can think of TFloat simply as Single. All existing code relies on it and it will not change.
