16.4 Size and precision of real values

6.4.2.2 b) The values of the real-type shall be an implementation-defined subset of the real numbers denoted by signed-real.

The real numbers described by the ISO/IEC 7185 have infinite range and infinite precision. Implementations are allowed to limit the maximum range and precision of real numbers.

Irie Pascal uses 64 bit reals stored as specified by the following standard: "IEEE standard for binary floating-point arithmetic (ANSI/IEC std 754-1985)".
