how to convert @[1..5] to @[1.0,2.0,3.0,4.0,5.0]?

[gemath]

Here comes the zero_functional solution: 
    
    
    import sequtils, zero_functional
    
    let s = toSeq(1..5) --> map(it.float).to(seq)
    
    
    Run

Complete overkill for this simple case, but I just won't stop plugging this 
ingenious lib. :o)
