	This routine rounds the (floating point) input to the nearest integer. It follows IEEE854 standards for rounding the number. The IEEE standard states that if a number is exactly in between two integers (y.5<s>0</s>) the output will be the nearest integer with an even least significant bit. This means that the number will be rounded to the nearest even integer.		This routine rounds the (floating point) input to the nearest integer. It follows IEEE854 standards for rounding the number.
