In the last example, the format of the real number returned as a
string is the same number but in a different representation. All real
numbers will be returned by the STR$ function in this format.
The string will always be 14 characters long with a sign
(+ or -), a decimal point (.), 8 digits (12345678), an exponent sign
(E), and 2 digits of exponent (XX). The sign character is always
present after this conversion even if the number is positive.

BINARY$ Function
Format:
BINARY$(expression)
where:
expression must be an integer or integer expression.
The function returns the binary form of the input as a string of 1s and
0s. For example:
BIT$=BINARY$(NUMBER_1%)ąą
7.14
HEX$ Function
Format:
HEX$(expression)
where:
expression must be an integer or integer expression.
The function returns the hexadecimal value of the input as a string.
For example:
HEX_VAL$=HEX$(X%)
7.15
LEFT$ Function
Format:
LEFT$(string,str_length)
where:
string can be a string variable or expression.
str_length is the number of characters to take from the left side
of the string (string expression) in parameter 1.
The function returns a substring that is equal to `str_length'
(parameter 2) of the leftmost characters of the string or string
expression (parameter 1):
SUB_STRING$ = LEFT$(`ABCDEFG',4) (SUB_STRING$
has the value ABCD)ąąą
STR1$ = `12345'
SUB_STRING$ = LEFT$(STR1$ + `ABC',6) (SUB_STRING$
has the value 12345A)
