Decimal v1.6.0

BEHAVIOR CHANGES

• Decimal implements fmt.Formatter. %#v prints Go code that recreates the value, like decimal.New(314, -2), instead of the struct fields, and verbs that don't apply, like %d, print %!d(decimal.Decimal=3.14). %v, %s, %q, %x and fmt.Println print the same as before #463
• Ln rounds correctly, so some results change in the last digit: Ln of 10 to 5 places is 2.30259, not 2.30258 #471
• ExpHullAbrham returns overallPrecision significant figures for every input. Negative inputs used to lose digits or return 0, like -50 at precision 10, and large inputs returned extra digits #429 #470
• Scan converts float32 with NewFromFloat32, so 54.33 stays 54.33 instead of becoming 54.33000183105469. NaN and infinite floats return an error instead of panicking #469
• On Go 1.10 to 1.12, NewFromFloat can pick a different shortest form in rare cases (golang/go#29491). It still converts back to the same float #431

FEATURES

• Add BSON Decimal128 support for Decimal and NullDecimal with the official MongoDB Go driver v2, without a new dependency #460
• Add %f formatting with precision, width and flags, like %.2f and %08.2f #463
• Add Normalize, which strips trailing zeros so equal decimals also match with reflect.DeepEqual, testify and gomock #464
• Add Sqrt and SqrtRound #465
• Add Root and RootRound for n-th roots #473
• Add NewFromBigFloat constructor #457
• Scan accepts Decimal, big.Int, *big.Int and all integer sizes, as passed by ClickHouse and other drivers #469

ENHANCEMENTS

• NewFromFloat and NewFromFloat32 are 3 to 6 times faster. They use strconv instead of a vendored copy of it from 2009, which is removed #431
• Ln is 3 to 14 times faster #471
• Slightly faster IsInteger and Ceil #299
• NewFromString accepts the Unicode minus sign − (U+2212) #428
• Scanning NULL into a Decimal returns an error that points to NullDecimal or *Decimal #474
• Document that global settings aren't goroutine-safe, and list them with their per-call alternatives in the README #466
• README: show how to control the JSON format of one field, add udecimal to the alternative libraries, and update the Go doc and playground links #475 #476 #264
• Fix doc examples that were wrong or didn't compile #468
• Fix benchmarks that measured their setup or the wrong function #467
