    `sprintf \synonym "format" .variable. [.variable. [...]]'
Write numbers into a synonym (text string). This is useful for labelling plots. ``sprintf \out "a = %lf b = %.2f" .a. .b.`' - Create a synonym called ``\out`', and print the values of the variables ``.a.`' and ``.b.`' into it. If ``.a.`' = 1 and ``.b.`' = 0.112, then ``\out`' will be ``"a = 1 b = 0.11"`' Formatting codes are as in the C programming language, eg:
    %.2f  -- Use floating point with 2 decimal places.
    %9.2f -- As above, but number takes 9 characters.
    %e    -- Use exponential notation.
CAUTION: Variables are stored in the floating point in Gri, so you must use a format like ``"%f"`', not an integer code like ``"%d"`'.
