The set of values of the type float is a subset of the set of values of the type double; the set of values of the type double is a subset of the set of values of the type long double. The C++ standard adds:
- What are the actual min/max values for float and double (C++)A double can store values from: Float's precision allows it to store a value of up to 9 digits (7 real digits, +2 from decimal to binary conversion) Double, like the name suggests can store twice as much precision as a float. It can store up to 17 digits. (15 real digits, +2 from decimal to binary conversion) e.g.
- java - Double vs. BigDecimal? - Stack OverflowSaying that "BigDecimal is an exact way of representing numbers" is misleading. 1/3 and 1/7 can't be expressed exactly in a base 10 number system (BigDecimal) or in base 2 number system (float or double). 1/3 could be exactly expressed in base 3, base 6, base 9, base 12, etc. and 1/7 could be expressed exactly in base 7, base 14, base 21, etc. BigDecimal advantages are that it is arbitrary ...
- What exactly does Double mean in java? - Stack OverflowA double is an IEEE754 double-precision floating point number, similar to a float but with a larger range and precision. IEEE754 single precision numbers have 32 bits (1 sign, 8 exponent and 23 mantissa bits) while double precision numbers have 64 bits (1 sign, 11 exponent and 52 mantissa bits).
- How to compare two double values in Java? - Stack OverflowBut if you use Double.compare, note that (1) If d1 and d2 both represent Double.NaN, then the method returns true, even though Double.NaN==Double.NaN has the value false; and (2) If d1 represents +0.0 while d2 represents -0.0, or vice versa, the method returns the value false, even though +0.0==-0.0 has the value true.
