If you need to use a large number, you can use a type specifierlong. Here's how: longa;longlongb;longdoublec; Here variablesaandbcan store integer values. And,ccan store a floating-point number. If you are sure, only a small integer ([−32,767, +32,767]range) will be used, y...
there is a possibility of overflow if this data type (long) has the same size as the other data type (int). This issue arises due to the absence of an assured size for such data types. However, you can avoid this problem by using data types likeint32_...
Octal integer preceded by 0 Hexadecimal integer preceded by 0x or 0X Integer suffix: L l stand for long int ul UL stand for unsigned long int 默认为int Real constant--float Decimal notation Exponential notation a *E(e)^n Suffix F or f -- float L or l -- long double 默认为double sy...
In C++, long is a data type for a constant or variable which has the capability of storing the variable or constant values with 64-bits storage and is signed integer data type which is used for storing variable or constants with larger values larger than standard integer 32-bit data type. ...
For illustration purposes, these examples showcase how the data type rules perform on a system whose largest integer is 32 bits. On theHardware Implementationpane of theConfiguration Parametersdialog,longis set to 32 bits and theSupport long longparameter is disabled. ...
long The long data type is a 64-bit signed two’s complement integer 5 float The float data type is a single-precision 32-bit IEEE 754 floating point 6 double The double data type is a double-precision 64-bit IEEE 754 floating point. 7 char The char data type is a single 16-bit ...
Name String Name of a spread placement group, which must be 1-60 characters long. Type String Type of a spread placement group. Valid values: HOST: physical machine. SW: switch. RACK: rack. CvmQuotaTotal Integer The maximum number of CVMs that can be hosted in a spread placement group....
Use the Long data type to contain integer numbers that are too large to fit in the Integer data type.The default value of Long is 0.Literal assignmentsYou can declare and initialize a Long variable by assigning it a decimal literal, a hexadecimal literal, an octal literal, or (starting ...

The integer data type is further divided intoshort,int, andlongdata types. The short data type takes 2 bytes of storage space; int takes 2 or 4 bytes, and long takes 8 bytes in 64-bit and 4 bytes in the 32-bit operating system. ...
