FloatingPointLiteralPrecision
Floating point literal loses precision

The problem

double and float literals that can’t be precisely represented should be avoided.

Example:

double d = 1.9999999999999999999999999999999;
System.err.println(d); // prints 2.0

Suppression

Suppress false positives by adding the suppression annotation @SuppressWarnings("FloatingPointLiteralPrecision") to the enclosing element.
