// An easy way to test if the floating-point operations are correct is to
|
||
|
|
// evaluate: 89255.0/1e22. If the floating-point stack is 64 bits wide then
|
||
|
|
// the result is equal to 89255e-22.
|
||
|
|
// The best way to test this, is to create a division-function and to compare
|
||
|
|
// the output of the division with the expected result. (Inlining must be
|
||
|
|
// disabled.)
|
||
|
|
// On Linux,x86 89255e-22 != Div_double(89255.0/1e22)
