在C或者java里面,double是64位浮点数,float 是32 浮点数: 1bit符号 8bit指数部分 23bit尾数。推荐阅读《JAVA 浮点数的范围和精度》 long与double在java中本身都是用64位存储的,但是他们的存储方式不同,导致double可储存的范围比long大很多 long可以准确存储19位数字,而double只能准备存储16位数字(实际测试,是17位...

Approximate data types, on the other hand, contain floating-point data types—for instance, 2-, 4-, and 8-byte integers, 4- and 8-byte floating-point numbers, and selectable-precision decimals.Explore more Azure database services Azure SQL Database Build apps that scale with the pace ...
Data types in Java Javahas two main data types: Primitive. Non-primitive. There are eight primitive data types: byte, short, int, long, float, double, char and bool. Byte, short, int and long all store whole numbers, although with different ranges. Float and double store fractions; char...
