LongFloats represent rational numbers with limited precision. |
7380 | 245 |
They use the C-compilers 'long double' format, which is usually |
21973 | 246 |
mapped to the IEEE extended precision or IEEE quadruple precision format. |
10333 | 247 |
|
7380 | 248 |
In contrast to Floats (which use the C-compilers 64bit 'double' format), |
21973 | 249 |
LongFloats give you 80 bit extended floats, 96 bit extended floats or 128 bit quadruple floats. |
17129 | 250 |
The actual number of bits depends on the underlying CPU. |
21973 | 251 |
Thus, code using longFloats is not guaranteed to be portable from one architecture to another. |
10333 | 252 |
|
13053 | 253 |
NO GARANTY: |
21973 | 254 |
on systems which do not support 'long doubles', LongFloats are (silently) |
255 |
represented as 'doubles'. |
