>Does anyone know the method VFP uses to encode the YYYYMMDD HH:MM:SS data into the 8 bytes of a DATETIME field? I haven't figured out DOUBLE yet either.
DateTime: I heard a claim somewhere that there is one byte each for century, year, month, day, hour, minute, second, 100th second. However, there seems to be no way to actually 100th. seconds, so this may not be entirely true.
For Double, you have to search the IEEE standars for floating-point numbers. Briefly, if I remember correctly, there is one bit for the sign, several for the exponent, several for the mantissa (do you know scientific notation?) - all this in binary.
