Single- and double-precision implementations for log function families
|
|
|
|
New `float` and `double` overloads of $(REF log, std, math, exponential),
|
|
$(REF log10, std, math, exponential), $(REF log1p, std, math, exponential),
|
|
$(REF log2, std, math, exponential), and $(REF logb, std, math, exponential)
|
|
have been added to Phobos with proper 'software' implementations in the
|
|
corresponding precision. Furthermore, $(REF logb, std, math, exponential) is
|
|
now `pure`.
|
|
|
|
While this may result in a slowdown in some cases for DMD, the overall speed-up
|
|
factor for GDC and LDC is over 3x, for both `double` and `float`.
|
|
|
|
This also implies less precise results, especially in single-precision,
|
|
so if your code depended on more accurate results via 80-bit intermediate
|
|
precision, you'll have to cast the argument(s) explicitly now.
