字串的 ASCII/ANSI 轉換

Asc Function (BASIC)

傳回字串型表示式中第一個字元的 ASCII 值 (美國資訊交換標準碼)。

Chr Function

傳回與指定字元代碼對應的字元。

Str Function

The Str function converts the contents of variables into a string. It handles numeric values, dates, strings and currency values.

Positive numbers are preceded by a blank space. Negative numbers are preceded by a minus sign.

For numeric values the string returned by the Str function is locale-independent. Hence the dot is used as the decimal separator when needed.

If a string is passed as argument, it is returned without any changes.

Dates are converted into locale-dependent strings.

Val Function

Use the Val function to convert a string that represents a number into numeric data type.

The string passed to the Val function is locale-independent. This means that commas are interpreted as thousands separators and a dot is used as the decimal separator.

CByte Function

Converts a string or a numeric expression to the Byte type.
