The reason for this output is that the “input” function always returns a string. So sure, we asked the user for a number, but we got the string ‘5’, rather than the integer 5. The ‘555’ output is thanks to the fact that you can multiply strings in Python by integers, getting...

textintegercharNumericNUMERIC数据类型是一种精确数字数据类型,其精度在算术运算后保留到最小有效位,numeric是标准sql的数据类型,格式是numeric(m,n)。numeric(a,b)函数有两个参数,前面一个为总的位数,后面一个参数是小数点后的位数,例如numeric(5,2)是总位数为5,小数点后为2位的数,也就是 数据库 SQL 数据...

Nonintegral data types are those that represent numbers with both integer and fractional parts.The nonintegral numeric data types are Decimal (128-bit fixed point), Single Data Type (Visual Basic) (32-bit floating point), and Double Data Type (Visual Basic) (64-bit floating point). They ...
Float vs. numeric While the purpose of the integer data type is clear, there is an important difference between the numeric type and the float4 / float8 types. Internally, float uses the FPU (floating point unit) of the CPU. This has a couple of implications: Float follows theIEEE 754 ...
