Vilma Software Hal - Integer data type

Integer data type

There is different type of integer values. Depends from the size they are:

  • int - signed integer value. It's size is system depended. For the Intel and AMD processors it is 32 bit (4 bytes) value.

  • unsigned int - unsigned integer value. just like above it's size depends from the system. Usually it is 32 bit (4 bytes) value.

  • signed short - 16 bit (2 bytes) signed value (also called word). Can be from 32,768 to 32,767.

  • unsigned short - 16 bit (2 bytes) unsigned value. Can be from 0 to 65,535.

  • long - 32 bit (4 bytes) signed value. Can be from 2,147,483,648 to 2,147,483,647.

  • unsigned long - 32 bit (4 bytes) unsigned value (also called dword). Can be from 0 to 4,294,967,295.

  • large integer - 64 bit (8 bytes) signed value (also called qword or _int64_t). Can be from -2^63 to 2^63-1.

The 8 bit values types are called "bytes".
The 16 bit values are often called "words".
The 32 bit values are often called "dwords".
The 64 bit values are often called "qwords"
