1. A neural network system comprising:
a data type converter configured to convert 32-bit floating-point format into one of a plurality of 16-bit floating-point formats; and
a multiplication and accumulation (MAC) operator configured to perform MAC operations using 16-bit floating-point format data converted by the data type converter,
wherein the MAC operator includes a data type modulator configured to modulate the bit number of the converted 16-bit floating-point format to provide a modulated floating-point format with bit number different from the bit number of the converted 16-bit floating-point format.
