This creates a 4x7 rank 2 array that contains doubles 示例中创建了包含双精度数的秩为2的4x7数组。
It provides nearly 400 functions for doubles and complex numbers 它为双精度数和复数提供了近400个函数。
Also , no function fills an array or matrix with random doubles 它也没有用随机双精度数来填充数组或矩阵的函数。
By employing its native capabilities , it is easy to implement and construct a random double filling function , as you can see from this example 通过使用它自身的功能可以容易地实现和构造随机双精度数填充函数,如下面的示例所示:
In addition to basic string support , you can store booleans , doubles , floats , integers , longs , and byte arrays think serialization 除支持基本的字符串之外,您还可以存储布尔值、双精度数、浮点数、整型数、长整型数和字节数组(考虑序列化) 。
