FPTaylor 0.9.4

  • [FEATURE] opt = auto: automatically select bb or bb-eval.

  • [FEATURE] --print-second-order-errors: an option for printing second order errors.

  • The performance of Taylor forms generation for large expressions is improved.

  • Removed proof recording. Use FPTaylor v0.9.3 for recording proofs.

FPTaylor 0.9.3

  • Minimal version of OCaml is increased to 4.03.

  • [FEATURE] --print-hex-floats: Printing important floating-point values as exact hexadecimal numbers.

  • [FEATURE] --export-options: Exporting all options into a given file.

  • [FEATURE] --print-precision: Error bounds are printed as correctly rounded decimal numbers with the given number of digits.

  • Moved tools/plot.py to scripts/plot/plot.py.

  • Added regression tests.

  • [FEATURE] bb-eval optimization: the same as bb but does not require an OCaml compiler to be installed.

  • ExprOut printer for JavaScript.

  • find-bounds = false by default.

  • bb and bb-eval: evaluate common subexpressions only once.

  • JavaScript version of FPTaylor and FPTaylor's website.

  • Maxima: the simplificaiton function is ratexpand now.

  • FPCore export: context annotations for mixed precision benchmarks.

  • export: A separate tool for exporting FPCore benchmarks.

FPTaylor 0.9.2

  • [FEATURE] ULP error (experimental; almost always suboptimal near powers of 2).

  • [FEATURE, can break existing FPTaylor input files] The rounding operation rnd without parameters can be used in input files. The rounding type is defined by the default-rnd option (the default value is rnd64). Parameters of rounding operations must be given in square brackets. (Parameters were in parentheses before.)

  • [FEATURE, can break existing FPTaylor input files] Variables without explicit types are assigned the default type defined by the default-var-type option (the default value is float64). (Variables without explicit types were assumed to be of the real type before.)

FPTaylor 0.9.1

  • [FEATURE] tools/plot.py: a script for plotting 1d error models.

  • [FEATURE] Exporting ErrorBounds input files.

  • [FEATURE] Exporting to the FPCore format.

  • [FEATURE] Several tasks in one files (inside curly braces).

  • [FIX] Correct rounding of constants which are representable as float64. It was possible to get incorrect results for rounding modes different from rnd64. For instance, the result of a = rnd32(1p+50 + 1) was err = 0.
