Built-in value type conversions

In order to protect from problems when converting or assigning value types, the following guidelines should be used at compile time and during the runtime (for dynamic assignments):

t as double = 3 # No error, implicit conversion from int to double does not cause loss of resolution

t as int = 3.0 # Error: no implicit conversion from double to int because that would cause a loss of resolution

t as long = 3
u as int = t # Error: no implicit conversion from long to int; loss of resolution

t as int = cast(int, 3.0) #No error, explicit conversion completes; programmer understands loss of resolution

t as long = 3
u as int = cast(int, t) # No error, explicit conversion completes; programmer understands loss of resolution

These conversion rules for the built-in types follow the conventions of C#

for the implicit conversion, the one-way order of implicit conversion goes:
byte -> int -> long -> single -> double -> decimal
