FormulaText[Object]:
Returns the formula for the object as a LaTeX text.
Example: If a = 2 and f(x) = a x2,
then FormulaText[f]
returns 2 x2 (as a LaTeX
text).
FormulaText[Object,
Boolean]: Returns the formula for the object as LaTeX text. The
Boolean variable determines if values are substituted for variables (true) or if variable names are shown in
the text (false).
Examples: If a = 2 and f(x) = a x2,
then
FormulaText[f, true] returns 2 x2 (as a LaTeX text).
FormulaText[f, false] returns a x2 (as a LaTeX text).
FractionText[Number]:
Converts the number to a fraction, which is displayed as a (LaTeX) text object
in the Graphics
View.
Example: If a: y = 1.5 x + 2 is a line, then FractionText[Slope[a]]
gives you the fraction 3/2 as a text.
LetterToUnicode["Letter"]: Turns a single letter
into its Unicode number
Note: The letter needs to be in between a set
of quotation marks.
Example: LetterToUnicode["a"]
returns the number 97
Name[Object]:
Returns the name of an object as a text in the Graphics View.
Note: Use this command in dynamic text for
objects that might be renamed. The Name command
is the opposite of the Object
command.
Object[Name
of Object as Text]: Returns the object for a given name. The
result is always a dependent object.
Note: The Object
command is the opposite of the Name command.
Example: If points A1, A2, ... , A20 exist and slider n = 2, then Object["A"
+ n] gives you a copy of point A2.
TableText[List
1, List 2, List 3,...]: Creates a text that contains a table of
the list objects.
Note: By default, every list is displayed in
a new column of the table.
Examples:
·
TableText[{x^2,
4}, {x^3, 8}, {x^4, 16}]
creates a table as a text object with three rows and two columns. All items of
the table are left aligned.
·
TableText[Sequence[i^2,
i, 1, 10]]
creates a table as a text object with one row. All items of the table are left
aligned.
TableText[List
1, List 2, List 3,..., "Alignment
of text"]:
Creates a text that contains a table of the list objects. The optional text
“Alignment of text” controls the orientation and alignment of the table text.
Note: Possible values are "vl",
"vc", "vr", "v", "h", "hl",
"hc", "hr". Default is "hl".
· "v" = vertical, i. e. lists are columns
· "h" = horizontal, i. e. lists are rows
· "l" = left aligned
· "r" = right aligned
· "c" = centered
Examples:
·
TableText[{1,2,3,4},{1,4,9,16},"v"]
creates a text with two columns and four rows whose elements are left aligned.
·
TableText[{1,2,3,4},{1,4,9,16},"h"]
creates a text with two rows and four columns whose elements are left aligned.
·
TableText[{11.2,123.1,32423.9,"234.0"},"vr"]
creates a text with one column whose elements are right aligned.
Text[Object]:
Returns the formula for the object as a text object.
Note: By default, values are substituted for
variables.
Example: If a = 2 and c = a2,
then Text[c]
returns the text "4".
Text[Object,
Boolean]: Returns the formula for the object as a text object. The
Boolean variable determines if values are substituted for variables (true) or if variable names are shown in
the text (false).
Example: If a = 2 and c = a2,
then
Text[c, true] returns the text "4".
Text[c, false] returns the text "a2".
Text[Object,
Point]: Returns the formula for the object as a text object at
the position of the given point.
Example: Text["hello",
(2, 3)] draws the text at the position (2, 3).
Text[Object, Point, Boolean]: Returns the formula for the object as a text object at the position of the given point. The Boolean variable determines if values are substituted for variables (true) or if variable names are shown in the text (false).
TextToUnicode["Text"]: Turns the text into a list
of Unicode numbers, one for each character.
Examples:
·
TextToUnicode["Some
text"] gives you the list of Unicode numbers
{83, 111, 109, 101, 32, 116, 101, 120,
116}.
· If text1 is "hello", then TextToUnicode[text1] gives you the list of Unicode numbers {104, 101, 108, 108, 111}.
UnicodeToLetter[Integer]:
Converts the integer Unicode number back into a letter which is displayed as a
text object in the Graphics View.
Example: UnicodeToLetter[97]
gives you the text "a".
UnicodeToText[List
of Integers]: Converts the integer Unicode numbers back into text.
Example: UnicodeToText[{104,
101, 108, 108, 111}] gives you the text "hello".
