LongFloats represent rational numbers with limited precision. |
24263 | 212 |
They use the C-compilers 'long double' format, which is either |
213 |
mapped to the IEEE extended precision (80bit) or IEEE quadruple precision format (128bit). |
|
10333 | 214 |
|
7380 | 215 |
In contrast to Floats (which use the C-compilers 64bit 'double' format), |
24263 | 216 |
LongFloats give you 80 bit extended floats, 96 bit extended floats or 128 bit quadruple floats, |
217 |
depending on the underlying CPU. |
|
21973 | 218 |
Thus, code using longFloats is not guaranteed to be portable from one architecture to another. |
10333 | 219 |
|
13053 | 220 |
NO GARANTY: |
24267 | 221 |
on systems which do not support 'long doubles', LongFloats are (silently) |
222 |
represented as 'doubles'. |
