FORMATTING FLOATING POINT NUMBERS

摘要

Flexible high-speed generation and formatting of application-specified strings in floating point and related formats is available through table-based base conversion which may be integrated with custom formatting, and through printf-style functionality based on separate control string parsing and specialized format command sequence execution.

1. A system comprising:
a processor; a digital memory in operable communication with the processor; and a module for formatting floating-point numbers using at least one of the following: (a) a powers of ten table containing 64-bit floating point numbers used to determine the magnitude of a number which is being formatted, with a 0.0 entry and multiple entries which are ascending powers of ten, (b) a table of indexes into said powers of ten table used to locate an entry in the powers of ten table which is a power of ten closest on one side to the number which is being formatted.
