LongFloats represent rational numbers with limited precision. |
24948 | 213 |
They use the C-compiler's 'long double' format, |
214 |
which is either mapped to the IEEE extended precision (80bit) |
|
24460 | 215 |
or IEEE quadruple precision format (128bit). |
10333 | 216 |
|
7380 | 217 |
In contrast to Floats (which use the C-compilers 64bit 'double' format), |
25027 | 218 |
LongFloats give you one of 80 bit extended floats, 96 bit extended floats or 128 bit quadruple floats, |
24263 | 219 |
depending on the underlying CPU. |
25027 | 220 |
Thus, code using longFloats is not guaranteed to be portable from one architecture to another, |
221 |
but faster than software emulations. |
|
222 |
||
223 |
NOTE: |
|
25036 | 224 |
on systems which do not support 'long doubles', LongFloats are (silently) |
225 |
represented as 'doubles'. |

This is much like #truncated, but avoids a (possibly expensive) conversion |
