Moseley / Moseley Instruments.\n\nLicense: to be determined\n\nThe aim of this library is to provide a signed fixed-point data type for logic simulation and synthesis as well as digital signal processing applications. It is based on 32-bit words and therefore needs a 32-bit platform to run efficiently.\n\n### Example: sqrt(2)\nUsing the bisection method, this library was used to determine the square-root of two with 2048 bits of precision. The exact value is between\n\n```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 / 2^2048```\n\nand\n\n```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 / 2^2048.```\n\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Ftrcwm%2Ffplib","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Ftrcwm%2Ffplib","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Ftrcwm%2Ffplib/lists"}
