X = a numeric value
S = significance parameter
FLOOR returns the largest integer that is less than
or equal to X. If the optional significance parameter
S is specified, FLOOR returns X rounded down
to the nearest multiple of S. When S is omitted
it is assumed to be 1. The mathematical formula
is given by:
XLFLOOR is designed to be compatible with the Excel FLOOR function. It is functionally equivalent to SpreadScript's native FLOOR, except that the parameter S is required.
If both X and S are specified, they must have the same sign, or an error is generated. S should not be set to 0, or an error will result.
FLOOR(5.5) = 5
FLOOR(3.14159, 0.01) = 3.14
FLOOR(E3) = -10, where E3 = -9.99
XLFLOOR(-9.99, 1) = Error!
XLFLOOR(-9.99, -1) = -9
FLOOR(-9.99, -1) = -9 (in Excel compatibility mode)
FLOOR(C17) = 1, where C17 = 1
Excel function: XLFLOOR is compatible with Excel's FLOOR (In Excel compatibility mode, the ``XL'' prefix is not used.)
