PowerShell: Get help on Type Conversion

I am a newbie, and am reading a copy of Windows PowerShell 2 for Dummies. Somewhere it suggests me to get help on type conversion. I tried:

get-help Type Conversion
get-help TypeConversion
get-help(typeconversion)

All without success. Can anyone advise how to get-help on type conversion? Thanks.

get-help
is for cmdlet help, not general help for type conversion. Powershell is very intelligent and try to convert it for you by best guess. e.g. if you type PS> $i = 3 + "4". Then it will convert automatically to integer and result is 7.If you type PS> $i = "4" + 3. The result of $i is "43" instead. So you need to know the rule of type conversion (priority, default etc) before you can get-help for related cmdlets.

get-help about_ | select name, synopsis | select-string type

to look for some topics available
