Web site management - JavaScript Programmer’s Reference The object space is defined
JavaScript Programmer’s Reference The object space is defined by an extent rectangle that surrounds the space occupied by it on the screen. An extent rectangle is the smallest rectangle that completely encloses the item. This property specifies the width of that extent rectangle. Obsolescent (Definition) A feature of the language that is no longer supported. Warnings: . If you use obsolescent functionality, your script may fail when it is deployed on other platforms. See also: Deprecated functionality Octal value (Definition) A numeric value based on a radix of 8. Availability: ECMAScript edition 3 An octal value is an integer composed of only the following characters: 0 1 2 3 4 5 6 7 Octal values are always prefixed by a zero character. The sequence carries over for the next increment when each column reaches the value 7. Thus: 00 01 02 03 04 05 06 07 010 011 012 Octal values have a historical significance from having been used in the earliest computer systems. However these days, they are particularly useful since they map quite conveniently to the binary system. Each octal digit corresponds to three binary digits. The most significant of the three octal digits does not have a full range since it contains a carry over bit and a three digit octal number actually represents a 9 bit value. However, an 8 bit value can be encoded conveniently if the range is limited to 0377 as a maximum. Hexadecimal values map far more conveniently although they are harder to compute mentally. 0 0 0 0 0 0 0 0 0 0 0 0 1604
