The number of "supported" digits is, however, much larger, for example float will usually support up to 38 decimal digits and double will support up to 308 decimal digits, but most of these digits … The IEEE 754-2008 standard defines 32-, 64- and 128-bit decimal floating-point representations. Like the binary floating-point formats, the number is divided into a sign, an exponent, and a significand. Unlike binary floating-point, numbers are not necessarily normalized; values with few significant digits have multiple possible representations: 1×10 =0.1×10 =0.01×10 , etc. When the significand is zero, the exponent can be any value at all.
