BYTES The number of bytes used to represent a double value. static final int MAX_EXPONENT Maximum exponent a finite double variable may have. static final double MAX_VALUE A constant holding the largest positive
In addition, this class provides several methods for converting a double to a String and a String to a double, as well as other constants and methods useful when dealing with a double.Since: JDK1.0 Field Summary Modifier and Type Field Description static int BYTES The number of bytes ...
In contrast,adoubleis a 64-bit double-precision floating-point type, requiring eight bytes of memory. While it demands more storage, this larger size allows it to represent values with higher precision and a broader range, making it indispensable for tasks involving complex calculations or large ...

wayne wrote: Since type long and type double both occupy 8 bytes, we used to in the olden days be able to use the same space for an array of long and an arrays of double. I suppose that there is no way to do that in java compared to the old FORTRAN. It didn't contain a long...
"A double is plenty large" -> Yes, when using exponent, larger than a long too but that size is really not needed in stats. twitter uses long. For reference, the 8 bytes used in java are https://www.quora.com/How-is-a-float-or-double-value-stored-in-memory-in-java Author deanor...
understand and program, it can be a bit less efficient. The added cost comes from the need to use a mutex on every call to the function. Exactly how much this costs depends greatly on the programming language, the operating system, and the underlying hardware. Refer to “How does a ...
