mtlb_int32
Matlab int32 emulation function
Description
Matlab and Scilab int32 behave differently :
- Beyong the main interval bounds, Scilab's
int32()wraps, while Matlab'smtlb_int32()saturates. - For non integer values, Scilab's
int32()truncates the fractional part, while Matlab'smtlb_int32()rounds to the nearest integer.
Let imin = -(2^16) = -2147483648 and imax = 2^16 - 1 = 2147483647.
