Origins of Marble. Marble is a metamorphic rock resulting from regional or at times contact metamorphism of sedimentary carbonate rocks, either limestone or dolostone. This metamorphic process causes a complete recrystallization of the original rock into an interlocking mosaic of calcite and/or dolomite crystals.
In mathematics and computing, hexadecimal (also base 16, or hex) is a positional numeral system with a radix, or base, of 16. It uses sixteen distinct symbols, most often the symbols 0 â 9 to represent values zero to nine, and A, B, C, D, E, F (or alternatively a, b, c, d, e, f) to represent values ten to fifteen.ne hexadecimal digit represents a nibble, which is half of an octet or byte (8 bits). For example, byte values can range from 0 to 255 (decimal), but may be more conveniently represented as two hexadecimal digits in the range 00 to FF. Hexadecimal is also commonly used to represent computer memory addresses.
For example, the hexadecimal value F4240 is equivalent to 1,000,000 in decimal and 1111 0100 0010 0100 0000 in binary. Another place hexadecimal is used is as an HTML color code to express a specific color.For example, a web designer would use the hex value FF0000 to define the color red.he hexadecimal number system, also called base-16 or sometimes just hex, is a number system that uses 16 unique symbols to represent a particular value. Those symbols are 0-9 and A-F.
