The number of digits attached to the number is irrelevant as long as we considering the first non-identical integer. For example:
[tex]6.32215 > 6.32214 \\ since \: 5 > 4[/tex]
Additionally some numbers are written with two decimals only, implying that there an infinite amount of unnecessary zeros attached at the end. For example:
[tex]6.32 = 6.320000000000000000...[/tex]
Now a more clear approach would be to compare these two numbers after attaching these zeros.
[tex]6.3200000000... \\ 6.2350000000...[/tex]
Comparing the first three digits,
[tex]320 > 235 \\ 6.32 > 6.235[/tex]
