Here's a little program demonstrating conversion functions:
import parseutils, os
func flt2arr (x: float64) : array[0..7, uint8] =
result = cast[array[0..7, uint8]](x)
func arr2flt (a: array[0..7, uint8]) : float64 =
result = cast[float64](a)
when isMainModule:
let params = commandLineParams()
var flt : float64
discard parseFloat(params[0], flt)
let ary = flt2arr(flt)
for u in ary:
echo(u)
let arr : array[0..7, uint8]
= [ary[0]+1, ary[1], ary[2], ary[3], ary[4], ary[5], ary[6], ary[7]]
echo(arr2flt(arr))
Run
