SYNTAX

FLOOR {ON|OFF|v}

INPUT

{ON}:	Turn floor option on but don't change value of floor.
OFF:	Turn floor option off.
v:	Turn floor option on and change value of floor.

DEFAULT VALUES

FLOOR 1.0E-10

DESCRIPTION

The floor option applies only when logarithmic scaling is being used. It applies to both the x and y axes. When this option is on, any data values less than the floor are set to the floor before plotting. By using a small positive value for the floor, errors in taking logarithms of non-positive numbers are avoided.
