Typedef TReal32

typedef float TReal32;

Support

Supported from 5.0

Description

32-bit floating point number, providing IEEE754 single precision on all EPOC implementations. TReal should normally be used in preference to TReal32.

Use of floating-point numbers should generally be avoided unless a natural part of the problem specification. Most EPOC implementations do not have a hardware floating point unit: as a result, their floating-point performance is hundreds of times slower than integer performance.
