format("<descript> expr")

        Converts expr according to the description. descript consists of a list of characters separated by commas:
        * format ignored.
        numeric: forced value.
        X: converted values.
Examples: format("<*,X> comment 123"); returns 123.

x=" \n";
y=format("<*,X,X,0.0> coordinates 1.0 2.0\n coordinates 11.0 22.0"); returns vector:
(1,2,0.0,11.0,22.0,0.0);
Allows, for example, by forcing z 0, to read a file foo in the form:
xyz 1.0 2.0 3.0
xyz 11.0 22.0 33.0

y=format("<*,X,X,0.0>",read(\"foo\")";

format("b",x);

        Converts integer x>0 in binary.

format("f",x);

        Converts binary x (list of 0 and 1) in integer.
Note:
Binary is expressed in 32 bits starting with the low weights.

Examples:

format("b",123); returns: (1,1,0,1,1,1,1,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,)
format("f",(1,1,1,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0)); returns 7

Use:

To convert ASCII data files into variables (anyflo format).

Example:

Given file foo containing:
1: 1.1 2.2
2: -1.1 10.7 3: 10.1 -12.4
x=format("<*,X,X,0.0>",read("toto")); returns vector x containing: (1.1,2.2,0.0,-1.1,10.7,0.0,10.1,-12.4,0.0)

format("m",x,y,x1,x2,y1,y2,m)

        Returns the sum of the matrix elements of m (x columns, ylines) located between the x1 and x2 columns and lines y1 and y2.

format("c",x,y,x1,x2,y1,y2,m)

        Returns the center of gravity of the matrix elements of m (x columns, ylines) located between the x1 and x2 columns and lines y1 and y2.

format("c",x,y,x1,x2,y1,y2,m,c)

        Returns the center of gravity of the matrix elements of m (x columns, ylines) located between the x1 and x2 columns and lines y1 and y2 and whose value is greater than c (white on black).

format("c",x,y,x1,x2,y1,y2,m,c,"<")

        Returns the center of gravity of the matrix elements of m (x columns, ylines) located between the x1 and x2 columns and lines y1 and y2 and whose value is lesser than c (black on white).
Note:
Must:
x1 >= 0 x1 < x
x2 >= 0 x2 < x
x1 <= x2
y1 >= 0 y1 < y
y2 >= 0 y2 < y
y1 <= y2
Example:
m=[1,12];
format("m",4,3,0,2,1,2,m; returns 48=5+6+7+9+10+11

format("<htm>")

        Returns the list of special characters and their HTML.

format("<htm>c")

        Returns the html code of the character c.

format("<htm>&codehtml;")

        Returns the character whose code is ;&codehtml;
Examples
format("<htm>à");
        Returns &agrave;
format("<htm>&agrave;");
        Returns à
Notes:
1) The correspondence between the html codes and the ASCII codes are stored in file code_htm.
2) It is possible to modify this file.
3) If the file htm does not exist the codes are initialized by default.

format name("nnn.eee")

Returns eee.
