I don't know how to "grate" a number ... numbers are not cheese. An infinite number of numbers are "greater" (larger) than 64. Likewise, an infinite number of numbers are not "greater" (in other words, less than) 64, starting with 63, 62, 61, ... Actually, there are an infinite numbers that are less than 64, but greater than 63, unless you specify "whole numbers".
There is no whole number but a infinite fractional numbers
