mysql_row[]取值转换有关问题，

mysql_row[]取值转换问题，急！

c语言中用mysql_row[]取mysql数据库中的值后（数据库中为浮点型），因为取出的值是字符串型（应该是字符串吧，用%S能打印），但我需要将取出的值转为浮点型进行计算处理，字符串无法处理，但不知道怎么转换，用atof函数转换也不正确，恳请高人！！ 急~ 谢谢~~

MYSQL_RES

This structure represents the result of a query that returns rows (SELECT, SHOW, DESCRIBE, EXPLAIN). The information returned from a query is called the result set in the remainder of this section. 

MYSQL_ROW

This is a type-safe representation of one row of data. It is currently implemented as an array of counted byte strings. (You cannot treat these as null-terminated strings if field values may contain binary data, because such values may contain null bytes internally.) Rows are obtained by calling mysql_fetch_row(). 

根据手册很清楚，MYSQL_ROW 就是一个string, 如果你想处理数据，建议用MYSQL_RES 

用mysql_query 执行你的select 然后用 mysql_store_result来处理。网上找个例子参考一下。
