Convert float to int in Julia Lang

Question

Is there a way to convert a floating number to int in Julia? I'm trying to convert a floating point number to a fixed precision number with the decimal part represented as 8bit integer. In order to do this, I need to truncate just the decimal part of the number and I figured the best way to do this would be to subtract the converted integer of x from floating point x:

  x = 1.23455
y = x - Int(x)
println(y)

y = 0.23455

Answer 1

I think you are looking for floor:

julia> x = 1.23455
1.23455

julia> floor(x)
1.0

julia> y = x - floor(x)
0.23455000000000004
