MySQL storesDECIMALvalues in binary format. SeeSection 12.21, “Precision Math”. In aDECIMALcolumn declaration, the precision and scale can be (and usually is) specified. For example: salaryDECIMAL(5,2) In this example,5is the precision and2is the scale. The precision represents the number ...
Convert decimal value to binary vector collapse all in page Description This function is part of Data Acquisition Toolbox™, and converts decimal values to binary data represented by a vector of 1s and 0s. To convert to binary data as a character vector, you can use the MATLAB®function...

(官方解释:Values for DECIMAL columns are stored using a binary format that packs nine decimal digits into 4 bytes)。 那有可能设置的位数不是9的倍数,官方还给了如下表格对照: ==表格什么意思呢,举个例子:== 1、字段decimal(18,9),18-9=9,这样整数部分和小数部分都是9,那两边分别占用4个字节; ...
arithmetic uses the same principles as decimal arithmetic but operates on each decimal digit separately. this can be less efficient than binary arithmetic but is necessary in applications where decimal values must be preserved precisely, such as in financial calculations. what is a binary shift ...
