Floating-Point Types, Formats, and Values The floating-point types arefloatanddouble, which areconceptually概念associated with thesingle-precision 32-bitanddouble-precision 64-bitformat IEEE 754 values and operations asspecified指定 inIEEE Standard for Binary Floating-Point Arithmetic, ANSI/IEEE Standard ...
Floating-Point Types, Formats, and Values The floating-point types are float and double, which are conceptually概念 associated with the single-precision 32-bit and double-precision 64-bit format IEEE 754 values and operations as specified指定 in IEEE Standard for Binary Floating-Point Arithmetic, A...
floating-point types are, however, represented in a completely different format from their C/C++ counterparts. As in C, Java floating-point values can be represented with an exponential portion. The float type in C is used to store asignedfloating-point number value.The exact size of the flo...
Java 虚拟机所支持的原始数据类型包括了数值类型(Numeric Types)、 布尔类型(Boolean Type § 2.3.4) 和 returnAddress 类型(§ 2.3.3) 三类。其中数值类型又分为整型类型(Integral Types, § 2.3.1)和浮点类型(Floating-Point Types, § 2.3.2)两种。 和Java语言不同,JVM的原始类型包括:数值类型、布尔类型、...
因此,Java数据类型(type)可以分为两大类:基本类型(primitive types)和引用类型(reference types)。primitive types 包括boolean类型以及数值类型(numeric types)。numeric types又分为整型(integer types)和浮点型(floating-point type)。整型有5种:byte short int long char(char本质上是一种特殊的int)。浮点类型有...
基本类型 包括布尔(boolean)类型、数值类型(numeric types)，数值类型又分为 整型(integer types) 和 浮点型(floating-point type)。整型有5种：byte、short、int、long、char(char本质上是一种特殊的int);浮点类型有float和double。所以基本数据类型分类如下:byte、short、int、long、float(单精度)、double(双精度)...
Floating point numbers Real numbers measure continuous quantities, like weight, height, or speed. Floating point numbers represent an approximation of real numbers in computing. In Java we have two primitive floating point types:floatanddouble. Thefloatis a single precision type which store numbers ...
C11 对浮点类型的规定如下：The C floating types match theIEC 60559formats as follows:— The float...
Integral - may be applied to Java integral types: byte, Byte, short, Short, int and Integer, long, Long, and BigInteger (but not char or Character) Floating Point - may be applied to Java floating-point types: float, Float, double, Double, and BigDecimal Date/Time - may be applied...
double: The 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 the Floating-Point Types, Formats, and Values section of the Java Language Specification. For decimal values, this data type is...
