Numeric
# quo(other) -> Rational | Float | Complex (1204.0) -
self を other で割った商を返します。 整商を得たい場合は Numeric#div を使ってください。
self を other で割った商を返します。
整商を得たい場合は Numeric#div を使ってください。
Numeric#fdiv が結果を Float で返すメソッドなのに対して quo はなるべく正確な数値を返すことを意図しています。
具体的には有理数の範囲に収まる計算では Rational の値を返します。
Float や Complex が関わるときはそれらのクラスになります。
Numeric のサブクラスは、このメソッドを適切に再定義しなければなりません。
@param other 自身を割る数を指定します。
//emlist[例][ruby]{
1.quo(3)... -
Encoding
:: Converter # primitive _ convert(source _ buffer , destination _ buffer) -> Symbol (904.0) -
エンコーディング変換のためのメソッドの中で、もっとも細かな扱いが可能なメソッドです。
エンコーディング変換のためのメソッドの中で、もっとも細かな扱いが可能なメソッドです。
可搬性を確保しつつ、不正なバイトや変換先で未定義な文字の扱いを細かに指定したいときは、Encoding::Converter#primitive_convert が唯一の方法になります。
@param source_buffer 変換元文字列のバッファ
@param destination_buffer 変換先文字列を格納するバッファ
@param destination_byteoffset 変換先バッファでのオフセット
@param destination_bytesize 変換先バッファの容量

Gem
:: Indexer # compress(filename , extension) (904.0) -
与えられたファイルを圧縮して保存します。
与えられたファイルを圧縮して保存します。
@param filename 圧縮対象のファイル名を指定します。

MonitorMixin
# new _ cond -> MonitorMixin :: ConditionVariable (904.0) -
モニターに関連付けられた、新しい MonitorMixin::ConditionVariable を生成して返します。
モニターに関連付けられた、新しい MonitorMixin::ConditionVariable を生成して返します。 -
String
# to _ r -> Rational (904.0) -
自身を有理数(Rational)に変換した結果を返します。
自身を有理数(Rational)に変換した結果を返します。
Kernel.#Rational に文字列を指定した時のように、以下のいずれかの形
式で指定します。
* "1/3" のような分数の形式
* "0.3" のような10進数の形式
* "0.3E0" のような x.xEn の形式
* 数字をアンダースコアで繋いだ形式
//emlist[例][ruby]{
' 2 '.to_r # => (2/1)
'1/3'.to_r # => (1/3)
'-9.2'.to_r # => (-46/5)
'-9.2E2'.to_r ... -
Time
# iso8601(fractional _ seconds = 0) -> String (904.0) -
XML Schema で定義されている dateTime として 表現される形式の文字列を返します。
XML Schema で定義されている dateTime として
表現される形式の文字列を返します。
XML Schema で定義されている dateTime として
表現される形式の文字列をパースするためのクラスメソッド
Time.iso8601, Time.xmlschema もあります。
@param fractional_seconds 小数点以下の秒の桁数を整数で指定します。
省略した場合は0 となります。
@return 以下の形式の文字列を返します。
//emlist{
CCYY-MM-DDThh:mm:ssTZD

Time
# subsec -> Integer | Rational (904.0) -
時刻を表す分数を返します。
時刻を表す分数を返します。
Rational を返す場合があります。
//emlist[][ruby]{
t = Time.local(2000,1,2,3,4,5,6)
p "%10.9f" % t.to_f # => "946749845.000005960"
p t.subsec #=> (3/500000)
//}
to_f の値と subsec の値の下のほうの桁の値は異なる場合があります。
というのは IEEE 754 double はそれを表すのに十分な精度を
持たないからです。subsec で得られる値が正確です。 -
