The set of numbers in Scilab can be extended by adding %inf (infinity) and %nan (not a number). This is done with the Scilab function ieee:
-->ieee()
ans =0.
We see the default floating-point exception mode to be zero
-->1/0
!--error 27 division by zero...
Let us now use the standard ieee floating-point exception mode:
-->ieee(2) -->1/0 ans = Inf
In this mode, 1/0 evaluates to infinity.
-->0/0 ans = Nan
In this mode, 0/0 also is handled gracefully.
