FLOOR.MATH Function in Excel 2013

This is the new function introduced in Excel 2013. This function is used to round a number down to the nearest integer or to the nearest multiple of significance. The syntax of this function is as follows: =floor.math(number,[significance]) where significance is optional. The significance indicates the multiple of the number to which we want to round off the number. For example if we will take =floor.math(23.3,5) then it will round the number 23.3 down to the nearest integer that is multiple of 5 (20) so it will return 20. If we will use =floor.math(65.2,5) then it will return a multiple of 5 (65).
