mtlb_int32

Matlab int32 emulation function

Description

Matlab and Scilab int32 behave differently :

  • Beyong the main interval bounds, Scilab's int32() wraps, while Matlab's mtlb_int32() saturates.
  • For non integer values, Scilab's int32() truncates the fractional part, while Matlab's mtlb_int32() rounds to the nearest integer.

Let imin = -(2^16) = -2147483648 and imax = 2^16 - 1 = 2147483647.

mtlb_int32 has not to be used for hand coded functions.

The function mtlb_int32(A) is used by mfile2sci to replace int32(A) when it is not possible to know what is the input while porting Matlab code to Scilab. This function then determines the correct semantic at run time.
