总的来说short、int、long、char、float、double 这六个关键字代表C 语言里的六种基本数据类型。当标识符由多个词组成时,每个词的第一个字母大写,其余全部小写。比如: intCurrentVal; 这样的名字看起来比较清晰,远比一长串字符好得多。

为了[color=red]进行数据类型转化,MySQL提供了CAST()函数[/color],它可以把一个值转化为指定的数据类型。类型有:BINARY,CHAR,DATE,TIME,DATETIME,SIGNED,UNSIGNED 示例: SELECT CAST(NOW() AS SIGNED INTEGER),CURDATE()+0; SELECT 'f'=BINARY 'F','f'=CAST('F' AS BINARY); 九、系统信息函数 DATABASE(...
For question 2., if it's a binary file,freadcan read the data as signed integer as is. Use: out = fread(fid, numvalues, *int16); If it's a text file, convert your hexadecimal string with: out = typecast(uint16(base2dec(hexstring, 16)),'int16'); ...
To calculate a signature for SigV4 Call the hash function with the result of the previous call as the key and the string to sign as the data. Use the derived signing key as the hash key for this operation. The result is the signature as a binary value. signature = hash(SigningKey, ...

Beginners who want to see what numbers look like in binary notation may enter this definition: : BINARY ( -- ) 2 BASE ! ; The new word BINARY will operate just like OCTAL or HEX but will change the number base totwo. On systems that don’t have the word OCTAL, experimenters may def...
