Method: When::Coordinates.to_deg_225

Defined in:
lib/when_exe/coordinates.rb

.to_deg_225(src, dir) ⇒ Numeric

60進->10進変換(1/225度単位)

Parameters:

  • src (String) —

    60進法で表した方向付きの数値

  • dir (String) —

    方向 (‘NS’ または ‘EW’)

Returns:

  • (Numeric) —

    10進変換した数値 (src が nil なら0.0を、Numeric なら 225*src を返す)
