This data type has got a size of 4 bytes. The internal format is hardly to read for human beings. The number area goes from about -10 to the 38th (power) up to -10 to the -38th (power), nought and then from 10 to the -38th (power) up to 10 to the 38th (power). Entering REAL constants you have to enter a point in every case, that means ‘8.0’and not ‘8’, otherwise your system interprets your entering as integer which leads to absurd results evaluating as REAL number.
