Hello, I am new to Julia, I worked in the past mostly in Python and a bit with JAVA, C and C++. My question is that in the code below I get InexactError. The conversion works fine with floats with .0 decimal and not with another decimal ? I found that I have to use floor() or other similar functions before conversion.
v::Float16 = 120.5
Int64(v)
The error:
InexactError: Int64(120.5)
Stacktrace:
[1] Int64(x::Float16)
@ Base .\float.jl:912
[2] top-level scope
The simple answer is that there are many results that you may want when converting the value 120.5 to a decimal and so you need to choose which one you want.
The most obvious choices are round (which has several rounding modes) or ceil/floor
From PEP 20 – The Zen of Python 
Explicit is better than implicit.
Thank you, it make sense yes.
Thank you, yes agreed 
julia> Float16(120.5)
Float16(120.5)
julia> round(Int64, Float16(120.5))
120
julia> round(Int64, Float16(120.5), RoundNearest)
120
julia> round(Int64, Float16(120.5), RoundNearestTiesAway)
121
Thank you.
