** New functions for dealing with complex numbers in C have been added.
The new functions are scm_c_make_rectangular, scm_c_make_polar,
scm_c_real_part, scm_c_imag_part, scm_c_magnitude and scm_c_angle.
They work like scm_make_rectangular etc but take or return doubles
directly.
** The function scm_make_complex has been discouraged.
Use scm_c_make_rectangular instead.
** The INUM macros have been deprecated. ** The INUM macros have been deprecated.
A lot of code uses these macros to do general integer conversions, A lot of code uses these macros to do general integer conversions,
