nunjucks - Render value to tenths place in nunjucks template?

Question

Using the round() filter I can achieve the correct precision to the tenths place as in

{{ value | round(1) }}

however I still want to display the tenths place if value is zero or a whole integer. (0.0 instead of 0, 3.0 instead of 3)

Is there a different method or other way to render all values to the tenths place?

Answer 1

添加您自己的过滤器

var env = nunjucks.configure(...

env.addFilter('round1', function(num) {
    if (!isNaN(num))
        return '???';

    return parseFloat(num).toFixed(1);    
});

用法

{{ value | round1 }}

Answer 2

这是自定义过滤器的逻辑，因为圆形过滤器不会为零或整数保持十分位：

nunjucks.configure().addFilter('tenths', function(num) {
        return parseFloat(num).toFixed(1);
    });

然后用法与任何过滤器相同：

{{ num | tenths }}
