FLOOR
 
Updated: 17 August 2010
Use FLOOR to calculate a number rounded down, towards zero, to the nearest multiple of significance. For example, it you are dealing with a currency for which there are no fractional units, the formula FLOOR(100.9, 1) would return 100.

   <@Number, float,>
 ,<@Significance, float,>)
