This document describes the floating-point data types.
TReal is a 64-bit double-precision type, used as the argument type for all math functions, and the default type of floating-point literals.
TReal64 and TReal32 are available when the precise size is important.
Symbian platform floating-point arithmetic conforms to the IEEE754 specification.
Most Symbian platform implementations do not have hardware floating-point support. As a result, floating-point arithmetic is noticeably less efficient than integer arithmetic. It should be avoided unless demanded by the problem type.
