Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current technologies face challenges in converting data from human-readable decimal formats to decimal floating point formats without loss of accuracy, particularly in processing environments where binary floating point limitations are encountered.
Innovation Solution
The implementation of computer-readable program code logic that converts decimal floating point data by separating and converting the significand and exponent into specific formats, using instructions such as Convert From Unsigned Packed and Convert From Signed Packed, to compose and decompose decimal floating point data, ensuring accurate representation in decimal floating point format.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If binary floating point format is used for data representation, then processing speed and hardware compatibility are improved, but accuracy in representing decimal fractions is deteriorated due to inherent limitations in binary representation
Solution Approach 1:
The patent introduces an intermediary conversion process that translates between binary floating point format and decimal floating point format. The converter acts as a mediator that receives binary floating point data, converts it to decimal floating point representation, and outputs the converted data, thereby preserving both the speed benefits of binary processing and the accuracy benefits of decimal representation.
Solution Approach 2:
The patent changes the fundamental parameter of numerical representation from binary to decimal floating point format. By altering the base system parameter from 2 to 10, the system maintains compatibility with human-readable decimal formats while enabling accurate representation of decimal fractions that cannot be precisely expressed in binary format.
2Measurement precision
If decimal floating point format is used for accurate decimal representation, then measurement precision is improved, but device complexity increases due to additional conversion requirements
Solution Approach 1:
The patent segments the conversion process into distinct functional components: a converter module that handles the binary-to-decimal floating point conversion, and existing binary floating point processing infrastructure that remains unchanged. This segmentation allows the system to incorporate decimal floating point capabilities without completely redesigning the existing processing architecture.
3Productivity
If direct conversion from human-readable decimal format to binary floating point is performed, then processing efficiency is improved, but manufacturing precision is deteriorated due to rounding errors and loss of accuracy
Solution Approach 1:
The patent introduces decimal floating point format as an intermediary representation between human-readable decimal input and binary floating point processing. Data flows from human-readable decimal format to decimal floating point format (preserving accuracy), then to binary floating point format (enabling processing), thereby maintaining precision throughout the conversion chain while preserving processing efficiency.

AI summary
A decimal floating point finite number in a decimal floating point format is composed from the number in a different format. A decimal floating point format includes fields to hold information relating to the sign, exponent and significand of the decimal floating point finite number. Other decimal floating point data, including infinities and NaNs (not a number), are also composed. Decimal floating point data are also decomposed from the decimal floating point format to a different format.
