1. A method for double precision approximation of a single precision operation, comprising the steps of: (A) storing an input value in a processor, wherein (i) said processor implements a plurality of first operations in hardware, (ii) each of said first operations receives a first variable as an argument, (iii) said first variable is implemented in a fixed point format at a single precision and (iv) said input value is implemented in said fixed point format at a double precision; and (B) generating an output value by emulating a selected one of said first operations using said input variable as said argument, wherein (i) said emulation utilizes said selected first operation in said hardware, (ii) said output value is implemented in said fixed point format at said double precision and (iii) said emulation is performed by a plurality of instructions executed by said processor.
