cscalar_to_polar — REPRCONV algebra op

• Data kinds: cscalar → pairs

• Call: import reprconv; reprconv.cscalar_to_polar(cscalar) (or opsreprconv.get("cscalar_to_polar"))

Usage

Complex scalar → polar form `pairs (1,2) = [|z|, arg z [deg]]. The exit from cscalar`.

`cplx_contour_integral / cplx_cauchy_value` が返す複素スカラは、

`measurement`(実スカラのみ)へ混ぜると下流が生 TypeError で落ちるので

型が分かれている。極形式の対にすると 1-D 語彙へ渡せる。

角度は度。:func:polar_to_cscalar と往復して実測 max|Δ| = 8.9e-16。

Args:

cscalar: complex(または複素 0-d 配列)。

Returns:

(1, 2) float64。

Raises:

ValueError: 複素スカラでない / 非有限。
