Could be a few things.

  * the docs may be broken (unlikely). Try without the trailing .0 to
see if that looks right.

It's a percentage value being cast to an INTEGER for SNMP. So...
  * it may be that you are only using 1% or 100% of a CPU by Squid.
Check this against other software displaying the machines CPU.

  * the casting may be broken and rounding a large decimal up.
