6.6.2.10 Complex Number Operations

Scheme Procedure: make-rectangular real_part imaginary_part ¶

C Function: scm_make_rectangular (real_part, imaginary_part) ¶

Return a complex number constructed of the given real-part and imaginary-part parts.

Scheme Procedure: make-polar mag ang ¶

C Function: scm_make_polar (mag, ang) ¶

Return the complex number mag * e^(i * ang).

Scheme Procedure: real-part z ¶

C Function: scm_real_part (z) ¶

Return the real part of the number z.

Scheme Procedure: imag-part z ¶

C Function: scm_imag_part (z) ¶

Return the imaginary part of the number z.

Scheme Procedure: magnitude z ¶

C Function: scm_magnitude (z) ¶

Return the magnitude of the number z. This is the same as abs for real arguments, but also allows complex numbers.

Scheme Procedure: angle z ¶

C Function: scm_angle (z) ¶

Return the angle of the complex number z.

C Function: SCM scm_c_make_rectangular (double re, double im) ¶

C Function: SCM scm_c_make_polar (double x, double y) ¶

Like scm_make_rectangular or scm_make_polar, respectively, but these functions take doubles as their arguments.

C Function: double scm_c_real_part (z) ¶

C Function: double scm_c_imag_part (z) ¶

Returns the real or imaginary part of z as a double.

C Function: double scm_c_magnitude (z) ¶

C Function: double scm_c_angle (z) ¶

Returns the magnitude or angle of z as a double.
