i just dabble so i often don't know what i don't know, however...
writing a short v ditty to print golden ratios and areas to optional significant figures. i use println to output.
seems in v println will output 3 digits after the decimal point!! i worked round by converting my float to str.
mut x := 4.123456789012345
places := 7
// not what i want
println('${math.round_sig(x,places):10}') // 4.123
// better:-)
println('${math.round_sig(x,places).str():10}') // 4.1234568
all this may be because i have no idea what i am doing:-)
