Matlab int32 emulation function


Matlab and Scilab int32 behave differently in some particular cases:

  • With complex input: Matlab int32 can be used with complex values what Scilab function can not.

  • With %inf: Matlab int32 returns 2147483647 and Scilab returns -2147483648.

  • With %nan: Matlab int32 returns 0 and Scilab returns -2147483648.

  • With -%nan: Matlab int32 returns 0 and Scilab returns -2147483648.

The function mtlb_int32(A) is used by mfile2sci to replace int32(A) when it was not possible to know what was the input while porting Matlab code to Scilab. This function will determine the correct semantic at run time. If you want to have a more efficient code it is possible to replace mtlb_int32 calls:

  • If A does not contain %inf, %nan or -%nan values mtlb_int32(A) may be replaced by int32(A)

Caution: mtlb_int32 has not to be used for hand coded functions.
