mtlb_int64
Matlab int64 emulation function
Description
Matlab and Scilab int64 behave differently :
- Beyong the main interval bounds, Scilab's
int64()wraps, while Matlab'smtlb_int64()saturates. - For non integer values, Scilab's
int64()truncates the fractional part, while Matlab'smtlb_int64()rounds to the nearest integer.
Let imin = -(2^32) = -9223372036854775808 and
imax = 2^32 - 1 = 9223372036854775807.
