# Java double precision rounding

- 1 = 1 -3. If zero or positive, the scale is the number of digits to the right of the decimal point. 2322 = 4 etc. For example: 101. Double-precision floating-point format is a computer number format, usually occupying 64 bits in computer memory; it represents a wide dynamic range of numeric values by using a floating radix point. The Double class wraps a value of the primitive type double in an object. 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. common lisp racket clojure emacs lisp; version used SBCL 1. 13 = 2 101. 2: Racket 6. 100 = 3 1. 130 = 3 1. 5: show version $ sbcl --version $ racket --version: displayed by repl on startup . During its 23 years, it was the most widely used format for floating-point computation. This Java math tutorial explains both the basic Java math operators as well as the more advanced Java Math class. A BigDecimal consists of an arbitrary precision integer unscaled value and a 32-bit integer scale. What does it mean? Immutable, arbitrary-precision signed decimal numbers. 6: Emacs 24. 1: Clojure 1. Is there any in built function in java to tell me how many decimal places in a double. The float data type is a single-precision 32-bit IEEE 754 floating point and the double data type is a double-precision 64-bit IEEE 754 floating point. An object of type Double contains a single field whose type is double. I am happy to convert to another type IEEE 754-1985 was an industry standard for representing floating-point numbers in computers, officially adopted in 1985 and superseded in 2008 by IEEE 754-2008
