Inserting a proxy read instruction in an instruction pipeline in a processor is disclosed. A scheduler circuit is configured to recognize when a produced value generated by execution of a producer instruction in the instruction pipeline will not be available through a data forwarding path to be consumed for processing of a subsequent consumer instruction. In this case, the scheduling circuit is configured to insert a proxy read instruction in the instruction pipeline to cause execution of an operation to generate the same produced value as was generated by previous execution of producer instruction in the instruction pipeline. Thus, the produced value will remain available in the instruction pipeline to again be available through a data forwarding path to an earlier stage of the instruction pipeline to be consumed by a consumer instruction, which may avoid a pipeline stall.

Following computations by at least one hardware floating-point operator, a convertToDecimalCharacterFromBinary hardware conversion circuit converts the result back to a human-readable decimal character sequence floating-point representation.
