java float存储结构 1、属性。 1. static float MAX_VALUE : 返回最大浮点数,在不同硬件平台中由Float.intBitsToFloat(0x7f7fffff)计算得出。 2. static float MIN_VALUE : 返回最小浮点数,在不同硬件平台中由Float.intBitsToFloat(0x1)计算得出。 3. static float NaN : 表示非数值类型的浮点数,在不同硬件...
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...
