convert/bytes

convert between strings and lists of integers

Calling Sequence

convert(expr, bytes)

Parameters

expr

-

string, symbol, list of integers, or floating point value

Description

convert, with second argument 'bytes', converts a string first argument into list of integers giving the byte values of the characters within the string.

If the first argument is a symbol (i.e. a simple name) and that symbol has not been assigned a value, it is treated as if it were a string.

Passing a list of integers as the first argument will produce a string consisting of the characters corresponding to the integers in the list. If the list contains a zero value, the string is truncated at that point.

A hardware floating point first argument is converted to a list of values corresponding to the 8-byte internal IEEE representation of the value.

A software floating point value is first converted to hardware floating point, and then converted to a list as described above.

Examples

>

ABC

(2)

An integer outside the range 1..255 appearing in the list truncates the conversion to a string at that point.
