In 1964 the GOST standards body of the Soviet Union defined the standard for encoding data. This standard allowed a variable character size - depending on the type of data being encoded. GOST 10859 only allowed uppercase characters. Subsequent Soviet standards included lowercase: # GOST 19768/74 # GOST 19768/87 # GOST 13052 These include the non-ASCII "⏨" ((Decimal Exponent Symbol ) U+23E8). It was used to express real numbers in Scientific notation. For example: 6.0221415⏨23. The "⏨" character was also part of the ALGOL programming language specifications, and was also incorporated into the then German character encoding standard ALCOR. GOST 10859 also included numerous other ''non-ASCII'' characters/symbols useful to ALGOL programmers, e.g.: ∨, ∧, ⊃, ≡, ¬, ≠, ↑, ↓, ×, ÷, ≤, ≥, ° & ∅. c.f. ALGOL operators(). The "␡" character served the same function as the "␡" in 7-bit ASCII. == 4-bit code: Binary coded decimal == 抄文引用元・出典: フリー百科事典『 ウィキペディア(Wikipedia)』 ■ウィキペディアで「GOST 10859」の詳細全文を読む スポンサード リンク
