1. A method of processing a set of binary values using at least one floating point processing module, the method comprising: generating a set of floating point processing module input bits from a value represented in a fixed point fractional format, each individual bit of at least a portion of said value determining a bit value of a corresponding individual bit in said set of floating point processing module input bits; operating the floating point processing module to perform at least one floating point processing computation using said generated set of floating point processing module input bits as an input to the at least one floating point computation, said floating point computation module producing from the processing of said set of floating point processing module input bits a second set of bits arranged in a floating point format; generating a set of fixed point processing module input bits from the second set of bits arranged in a floating point format; and operating the fixed point processing module to perform at least one fixed point processing computation using said generated set of fixed point processing module input bits.
