> JsonSlurperCharSource decimal parsing producing unexpected results
> ------------------------------------------------------------------
>
> Key: GROOVY-7665
> URL: https://issues.apache.org/jira/browse/GROOVY-7665
> Project: Groovy
> Issue Type: Bug
> Components: JSON
> Affects Versions: 2.4.5
> Reporter: John Wagenleitner
> Priority: Minor
>
> When using the JsonParserType.CHARACTER_SOURCE decimal numbers are first
> parsed to double value and that value is used to construct the BigDecimal to
> return. This can produce some unexpected results.
> For example:
> {code}
> import groovy.json.*
> def parser = new JsonSlurper().setType(JsonParserType.CHARACTER_SOURCE)
> def json = parser.parseText('{"num": 123.40}')
> assert json.num instanceof BigDecimal
> assert 123.40G == json.num
> {code}
> Fails with:
> {code}
> Assertion failed:
> assert 123.40G == json.num
