FLOOR

FLOOR 1:

The FLOOR function determines an integral value from a floating point number that is a fraction smaller than or equal that number. The resulting number is of type LREAL and is therefore not limited to the value range of integer variables.

Examples

FLOOR(2.8) = 2

FLOOR(-2.8) = -3

Similar functions: TRUNC, LTRUNC

FLOOR 2:

Unlike FLOOR, the LTRUNC function always determines the integral part of a number. For positive values, this number is smaller than or equal the input parameter, for negative values it is greater than or equal the input parameter.
