Numeral.JS zeroFormat includes $ and % symbol at end result

Question

Why does zero formatting include $ and % symbols in the formatted result? numeral.js version is 1.5.3

var number = numeral(0);

numeral.zeroFormat('N/A');

var zero = number.format('0.0%')
// 'N/A%'

var zero = number.format('$0.0')
// '$N/A'

// What I expect is 'N/A'

Is it a bug or am I missing something?

Answer 1

Quickly found the solution. This problem happens in the older version. Just have to move to the latest version:

var number = numeral(0);

numeral.zeroFormat('N/A');

var zero = number.format('0.0%')
// 'N/A'
