logBase
calculation
0.4.3 July 18th 2016
- Fixes bugs:
- False positive: "f :: (CLog 2 (2 ^ n) ~ n, (1 <=? n) ~ True) => Proxy n -> Proxy (n+d)"
0.4.2 July 8th 2016
- Find more unifications:
(2*e ^ d) ~ (2*e*a*c) ==> [a*c := 2*e ^ (d-1)]
a^d * a^e ~ a^c ==> [c := d + e]
x+5 ~ y ==> [x := y - 5]
, but only when x+5 ~ y
is a given constraint
0.4.1 February 4th 2016
- Find more unifications:
F x y k z ~ F x y (k-1+1) z
==> [k := k], where F
can be any type function
0.4 January 19th 2016
- Stop using 'provenance' hack to create conditional evidence (GHC 8.0+ only)
- Find more unifications:
F x + 2 - 1 - 1 ~ F x
==> [F x := F x], where F
can be any type function with result Nat
.
0.3.2
- Find more unifications:
(z ^ a) ~ (z ^ b) ==> [a := b]
(i ^ a) ~ j ==> [a := round (logBase i j)]
, when i
and j
are integers, and ceiling (logBase i j) == floor (logBase i j)
.
0.3.1 October 19th 2015
- Find more unifications:
(i * a) ~ j ==> [a := div j i]
, when i
and j
are integers, and mod j i == 0
.
(i * a) + j ~ k ==> [a := div (k-j) i]
, when i
, j
, and k
are integers, and k-j >= 0
and mod (k-j) i == 0
.
0.3 June 3rd 2015
- Find more unifications:
<TyApp xs> + x ~ 2 + x ==> [<TyApp xs> ~ 2]
- Fixes bugs:
- Unifying
a*b ~ b
now returns [a ~ 1]
; before it erroneously returned [a ~ ]
, which is interpred as [a ~ 0]
...
- Unifying
a+b ~ b
now returns [a ~ 0]
; before it returned the undesirable, though equal, [a ~ ]
0.2.1 May 6th 2015
- Update
Eq
instance of SOP
: Empty SOP is equal to 0
0.2 April 22nd 2015
- Finds more unifications:
(2 + a) ~ 5 ==> [a := 3]
(3 * a) ~ 0 ==> [a := 0]
