EXTENDED DESCRIPTION
For an octal integer mode operand, the file mode bits shall be set absolutely.

For each bit set in the octal number, the corresponding file permission bit 
shown in the following table shall be set; all other file permission bits 
shall be cleared. For regular files, for each bit set in the octal number 
corresponding to the set-user-ID-on-execution or the 
set-group-ID-on-execution, bits shown in the following table shall be set; if 
these bits are not set in the octal number, they are cleared. For other file 
types, it is implementation-defined whether or not requests to set or clear 
the set-user-ID-on-execution or set-group-ID-on-execution bits are honored.
