float数据类型取值范围 java 浮点数据类型取值范围 in Java 在Java编程语言中,float数据类型用来表示单精度浮点数,通常用于存储小数。float数据类型的取值范围是有限的,这取决于其内部表示方式。在Java中,float类型的取值范围是从1.4e-45到3.4028235e+38。 float数据类型的内部表示 在计算机中,浮点数的表示采用IEEE 754...

Das Schlüsselwortfloatin Java ist ein primitiver Datentyp, der ein einfaches 32-Bit-Gleitkomma nach IEEE 754 darstellt. Er wird verwendet, um in großen Arrays von Fließkommazahlen Speicherplatz zu sparen und ist weniger genau als der Datentypdouble. ...
Java provides two primitive data types for floating-point arithmetic:floatanddouble. Both adhere to theIEEE 754standard, ensuring consistent behavior across platforms. However, their size, precision, and performance differ significantly. 2.1.Memory Size ...

since its introduction in java 8, the stream api has become a staple of java development. the basic operations like iterating, filtering, mapping sequences of elements are deceptively simple to use. but these can also be overused and fall into some common pitfalls. to get a better ...
作为一个常识,我们都知道浮点型在内存中占用的是4个字节的空间,而long型占用的是8个字节的空间。可是为什么今天在写JAVA程序时犯了一个错误,最后才知道4个字节的float型的最大值会大于long型的最大值。发现了这个错误我很吃惊,于是查资料才知道原因。
