I have x as double, hh as int32

in VBA I can perfom hh=Int(x) (narrowing conversion but disallowed in .NET)

One example in .NET is hh = System.Convert.ToInt32(x)

Could I use IConvertible and how would I code this?

Which is the better method keeping in mind that I would also be coding
calculations in hours/minutes/seconds, degress/minutes/seconds, radians and
logarithms. I would not want to lose too much precision in my results.

Regards
 
In .Net doubles are not precise, I recommend decimals. If you have option
strict enabled then:

Dim x a decimal, hh as integer

hh = ctype(int(x),integer)
or
hh = ctype(x,integer)
or
if not integer.tryparse(x,hh) then msgbox("Cannot parse.")

Check out 'CInt' too, which is maybe what you are looking for.
