Editing Hex Editing - Guide (section)

=== Numbers ===
All (or almost all) numbers are written in Little Endian - the bytes are placed in reverse order. As an example, 0xA624C (0x before a number signifies it's hexadecimal) in Little Endian is written as 4C 62 0A 00. Note, that the system recognizes that a number is negative based on the fact that it's greater than half the number range: greater than 0x80 for a single byte, and greater than 0x80000000 for a 4-byte value. 

Some numbers use a IEE-754 coding. It is recommended to use a calculator for such values, such as the one available on [https://www.save-editor.com/tools/converter_ieee_754.html save-editor.com]. 

Keep in mind that most (but, surprisingly, not all) lists start at 0, not at 1, so the first element is element 0 and not element 1.

QWORD and DWORD pointers are Little Endian representations of an address within the *.exe file, with 0x400000 added to them because of the way the game reads the code. Therefore if you want the DWORD pointer to find 0x27e484, you write it as 84 e4 67 00. DWORDs use IEE-754, while QWORDs use an 8-byte double-precision IEE-754 value. 

Values followed by zeroes in the same block are 4-byte numbers - this essentially increases their available number range from (in decimal) 0-127 to 0-2147483647.
