`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"'.
If you want an integer, use `"%.0f"'.
