(but there is no guaranty). |
1 | 143 |

Notice, that Floats are defined as Byte-array to prevent the garbage collector |
145 |
from going into the value ... otherwise I needed a special case in many places. |
|
146 |
||
147 |
Also notice, that ST/X Floats are what Doubles are in ST-80 - this may change |
|
148 |
in one of the next versions (at least on machines, which provide different float |
|
149 |
and double types in their C-compiler. |

WARNING: |
|
152 |
The layout of float instances is known by the runtime system and the compiler; |

153 |
you may not add instance variables here. |

errorHandling |
|
178 |
" |
|
179 |
Floating point error handling and signalling depends on the systems |
|
180 |
(actually: the C-runtime systems) ability to handle floating point errors. |
|
181 |
Most systems report errors by raising an OS floatingPoint exception, |
|
182 |
which is mapped to a fpExceptionInterrupt in ST/X. |
|
183 |
However, some systems do return NaN as result. |
|
184 |
||
185 |
Currently, ST/X does not care specially for these systems - it maybe added |
|
186 |
easily, if there is sufficient customer interest, though. |
