java:S2111 - "BigDecimal(double)" should not be used

[jpfroud (Jean-Pierre Froud)]

Rule java:S2111 recommends this as a compliant solution:

double d = 1.1;
BigDecimal bd1 = BigDecimal.valueOf(d);

But the result isn’t precise when using

double d = 1.0000000000000001
BigDecimal bd1 = BigDecimal.valueOf(d); -> 1.0

The only compliant solution should be new BigDecimal(String)

How to Report a False-positive / False-negative

What is a false-positive (FP)? A false-positive is when an issue is raised unexpectedly on code that should not trigger an issue, or where the suggested action doesn’t make any sense for the code. What is a false-negative (FN)? A false-negative is when an issue should be raised on a piece of code, but isn’t…

Specifically, we’re missing what version of SonarQube you’re using.
