Sanity4J was created to simplify running multiple static code
analysis tools on the Java projects. It provides a single entry
point to run all the selected tools and produce a consolidated
report, which presents all findings in an easily accessible
manner.

FE: Test for floating point equality (FE_FLOATING_POINT_EQUALITY)
FE: Test for floating point equality (FE_FLOATING_POINT_EQUALITY)
This operation compares two floating point values for equality.
Because floating point calculations may involve rounding,
calculated float and double values may not be accurate.
For values that must be precise, such as monetary values,
consider using a fixed-precision type such as BigDecimal.
For values that need not be precise, consider comparing for equality
within some range, for example:
if ( Math.abs(x - y) < .0000001 )
.
