Offset binary
The "characteristic" (exponent) took the form of a seven-bit excess-64 number (The high-order bit of the same byte contained the sign of the significand).A simple solution to this is to bias the analog signals with a DC offset equal to half of the A/D and D/A converter's range.[5] Most standard computer CPU chips cannot handle the offset binary format directly[citation needed].CPU chips typically can only handle signed and unsigned integers, and floating point value formats.The data may also be converted to signed integer format (which the CPU can handle natively) by simply subtracting the zero offset.
