“[DecimalPoint[Exponent[NegativeSign]]]” is a string of 0 to 3 characters. The rst one will be

used for the decimal point, the second for the exponent and the last one for the negative sign.

If DotZero is non-zero, then numbers are displayed in the form .1 instead of 0.1

If SizeLimit is specied, the command will attempt to generate a representation of the number that ts in

the given number of pixels. You can also specify the font size (10 to 22) and properties (bold, italic and mono-

spaced being Boolean values with 0 being false). There is no guarantee that the result will t, but the

command will attempt to make it t.

Examples:

String Result

string(F1), when F1(X) = COS(X) "COS(X)"

STRING(2/3) 0.666666666667

string(L1) when L1 = {1,2,3} "{1,2,3}"

string(M1) when M1 = "[[1,2,3],[4,5,6]]"

INSTRING

Syntax: INSTRING (str1,str2)

Returns the index of the rst occurrence of str2 in str1. Returns 0 if str2 is not present in str1. Note that the

rst character in a string is position 1.

Examples:

INSTRING ("vanilla","van") returns 1

INSTRING ("banana","na") returns 3

INSTRING ("ab","abc") returns 0

LEFT

Syntax: LEFT (str,n)

Return the rst n characters of string str. If n ≥ DIM(str) or n < 0, returns str. If n == 0 returns the string.

Example: LEFT("MOMOGUMBO",3) returns "MOM"

RIGHT

Syntax: RIGHT(str,n)

Returns the last n characters of string str. If n <= 0, returns empty string. If n > DIM(str), returns str

Example: RIGHT("MOMOGUMBO",5) returns "GUMBO"

MID

Syntax: MID(str,pos, [n])
