How do i prefix inside a v-model.lazy?

i’d like to be able to prefix the following with a currency sign, since it’s money we’re talking about here… how do i do that INSIDE the v-model.lazy?

here’s the HTML:

<input type="text" name="costToInvade" class="form-control" 

the desired output would be simply $123.00. i can’t change the data, because that comes in externally as just an float value. sooo… how can this be done?

and yes @skirtle, i checked my brackets, parenthesis, and commas. :smiley:
