Type conversions (numerical)
We have used conversion in previous examples. Type conversion refers to changing the type of the variable, but keeping the value of the variable the same:
#creating a 8-bit Integerjulia> Int8(100)100#we will get an error here as we exceed the size of the Int8julia> Int8(100*10)ERROR: InexactError()in Int8(::Int64) at ./sysimg.jl:53#this is solved by using Int16julia> Int16(100*10)1000#create a variable x of type Int32julia> x = Int32(40); typeof(x)Int32#using type conversion, convert it to Int8julia> x = Int8(x); typeof(x)Int8
We were successful, as 40 is in the range of the signed Int8.
