From 84f8c0cc1fbe1ab9c128555392a82ba609820fef Mon Sep 17 00:00:00 2001 From: kiel barry Date: Tue, 29 May 2018 03:42:21 -0700 Subject: common: improve documentation comments (#16701) This commit adds many comments and removes unused code. It also removes the EmptyHash function, which had some uses but was silly. --- common/math/big.go | 5 ++--- 1 file changed, 2 insertions(+), 3 deletions(-) (limited to 'common/math') diff --git a/common/math/big.go b/common/math/big.go index 787278650..dbf2770a9 100644 --- a/common/math/big.go +++ b/common/math/big.go @@ -78,7 +78,7 @@ func ParseBig256(s string) (*big.Int, bool) { return bigint, ok } -// MustParseBig parses s as a 256 bit big integer and panics if the string is invalid. +// MustParseBig256 parses s as a 256 bit big integer and panics if the string is invalid. func MustParseBig256(s string) *big.Int { v, ok := ParseBig256(s) if !ok { @@ -186,9 +186,8 @@ func U256(x *big.Int) *big.Int { func S256(x *big.Int) *big.Int { if x.Cmp(tt255) < 0 { return x - } else { - return new(big.Int).Sub(x, tt256) } + return new(big.Int).Sub(x, tt256) } // Exp implements exponentiation by squaring. -- cgit
