v2.1.3

Fixes #185.

v2.1.2

Fixes issue #180.

v2.1.1

Changes since v2.1.0:
Incorporated #174, fixed cbrt and root to allow roots of negatives as suggested in #176, and fixed #172.

v2.1.0

Sorry for not making this release earlier, I forgot to do so when I made the update!

• Added penta_log and linear_penta_root (the two inverses of pentation)
• Added the "floored" parameter to mod (when this parameter is true, it performs floored modulo instead of truncated division modulo)
• Fixed several issues ( #166, #167, #170, and #171 ); #170 in particular is a new feature, that being constants for the maximum value of a Decimal.

v2.0.0

A summary of changes from v1.4.2:

• Added a parameter to lambertw allowing you to calculate the non-principal branch
• Changed all cases where a constant or parameter is returned directly, to reduce the likelihood of accidental mutation
• Changed how tetration for bases <= e^1/e works: now the property x^^(n + 1) == x^(x^^n) always holds, and small bases with large payloads behave correctly.
• Fixed inaccuracies in f_gamma
• Decimal.dNegInf is now {-1, Infinity, Infinity} instead of {-1, -Infinity, -Infinity}. This one is a breaking change, hence the version number is now v2.0.0.

v1.4.2

A mistake was made in v1.4.1 - MathCookie17 thought Decimal.dNegInf was {-1, Infinity, Infinity}, but actually it's {-1, -Infinity, -Infinity}. This mistake should be fixed now.

v1.4.1

Thanks to MathCookie17.

Changes made:

• normalization for infinities and NaN
• ssqrt now uses linear_sroot rather than the other way around
• Added a linear hyper4 parameter to fromString
• Static versions of layeradd and slog now use DecimalSource for base instead of number, like their non-static versions. Also, added static trig functions
• Added JSDocs documentation for most functions

v1.4.0

Added the following features:

• An argument for hyper-4 functions that, when set to true, has them use the linear approximation even for bases <= 10, ensuring consistent behavior in situations where consistent behavior is needed (such as in an incremental game that uses tetration)
• Support for XFY format in fromString
• mod/modular function
• Super roots of arbitrary length (but only for the linear approximation, as super roots don't really work without a consistent definition of tetration)

v1.3.2

fixed slog, oops

v1.3.1 - the 'slog CAN be solved' edition

tetration and slog accuracy improved, see #108

Further improvements to tetration are possible by copying http://myweb.astate.edu/wpaulsen/tetcalc/tetcalc.html code, and performance improvements should be possible too, but this is a nice big improvement.
