Disclosed is a program that performs 16-bit floating point mathematical operations with a signed 8-bit exponent in an 8-bit microprocessor. By using the processor's 8-bit arithmetic commands and providing proper carry propagation, rounding, normalization, shifting, truncation and exponent adjustment, a processor's data width is expanded allowing increased bit-width operations.
