return 0; } 输出结果为: python The integer value of 123 is 123 需要注意的是,atoi函数只能将合法的整数字符串转换为整数类型,如果字符串中包含非数字字符,则转换结果可能不正确。此外,atoi函数只能处理整数类型的转换,如果需要将其他数据类型转换为字符串,可以使用其他的类型转换函数或字符串拼接函数。©...
CAST()函数的参数是一个表达式,它包括用AS关键字分隔的源值和目标数据类型。 语法:CAST (expression AS data_type) expression:任何有效的SQServer表达式。 AS:用于分隔两个参数,在AS之前的是要处理的数据,在AS之后是要转换的数据类型。 data_type:目标系统所提供的数据类型,包括bigint和sql_variant,不能使用用户...
比如说: (1)数据库存的数字是:25.56985 那么展现的形式应该就是:25.56% (2)数据库存的数字是:167.2323 那么展现的形式应该是:167.23% 那么问题来了 改如何处理呢? (1)CAST () 语法:CAST (expression AS data_t... 查看原文 C++:18---强制类型转换(static_cast、const_cast、dynamic_cast、reinterpret_cast...
