- % Format is a style option which allows the printing of floating point
- % numbers in fixed format. The argument is the counter to use. The
- % optional first argument if the power of ten to multiply counter by. The
- % default is 0. An integer is produced if power is nonnegative.
- % Otherwise, at least one digit appears before decimal point and exactly
- % -power digits after decimal point. Restriction: abs(power)<=6.

- % Example: label an axis with -1.0, -0.8, -0.6, ... 1.0
- % \newcounter{axis} \setcounter{axis}{-10}
- % \multiput(...)(...){11}{\format[-1]{axis}\addtocounter{axis}{2}}
