!!RDD - Round Down 

Round Down uses similar logic to Round Nearest, but rounds down to the last level specified in Operand 3

Examples			
||Operand 2||Operand 3||Result (stored in Operand 1)
|1.10011|		 1|	1
|1.10011|		0.001|	1.100
|1.1	|	0.5	|1.0
|1.0|		0.5|	1.0
|1.9|		0.5|	1.5

As with [RDN|RDN_OPERATOR], it is acceptable to round down to the next .25, or any other amount such as to the next 2, 3, etc. 

Statement: Round the value of PC 500 down to the nearest quarter hour and store it back into itself.
