float data type is a single-precision 32-bit IEEE 754 floating point.
Its range of values is beyond the scope of this discussion, but is specified in section
4.2.3
of the Java Language Specification. As with the recommendations for byte and short, use a float (instead of double) if you need to save memory in large arrays
of floating point numbers. This data type should never be used for precise values, such as currency. For that, you will need to
use the
java.math.BigDecimal
class instead.
Numbers and Strings
covers BigDecimal and
other useful classes provided by the Java platform.
double data type is a double-precision 64-bit IEEE 754 floating point.
Its range of values is beyond the scope of this discussion, but is specified in section
4.2.3
of the Java Language Specification. For decimal values, this data type is
generally the default choice. As mentioned above, this data type should never be used for precise values, such as currency.
