internal number representation
Hello all,
I still have some question about the internal representation of real numbers in the Prime. there is (in BCD): 1 nibble for the sign (4 bits) 12 nibbles for the mantissa 3 nibbles for the signed exponent How is the sign represented within the 4 sign bits? What can these 4 bits represent (+ infinity, infinity, ...) and how will it be done? How is the signed exponent represented within the 3 BCD nibbles? Is it shifted by 499, so 499 will be 000, 0 will be 499 and +499 will be 998? Is it possible to have a detailed description of the significance of the various bits? Is there a way to see the internal binary representation of a real number (something like casting a real to a longint)? Thank you very much for the help, I want to explain it to my students, but I'm not sure about how it will be done and don't want to expose it wrong. Reto
