Description

For example:
System.out.println(NumberUtils.createNumber("193343.82"));

The result is 193343.81。

The bug because of code in the class NumberUtils of the org.apache.commons.lang3.math package。

public static Float createFloat(final String str) {
if (str == null)

{ return null; }

return Float.valueOf(str);
}
