How serialized value is calculated for moveTo command in SkPath

[laxman-stan]

let's say I have a path

    let path = Skia.Path.Make().moveTo(0,0).lineTo(0,0);
    let cmds = path.toCmds();

the value of cmds will be

[
    [0, 3.2190260959738615e+38, -1.192110090642018e-7],
    [1, 0, 0]
]

the second item of the array is understandable
where
first value 1 represents lineTo command
and later are x and y values

but for the moveTo command
how these two values [3.2190260959738615e+38, -1.192110090642018e-7]
were calculated

and every time I log this
it return a slightly different value.

And it also varies from device to device
