Force decimal dot in g:field

Question

I'm new with grails, I have a g:field for a price input, the problem is that the user can enter a number with comma, for example if user enter 4,23 it will be processed as 423. How can I force to the user enter a dot instead of comma? Or are there some way to convert the comma in the input number to a dot?

This is my grails tag:

<g:field type="number decimal" min="0" maxFractionDigits="2" roundingMode="HALF_DOWN" name="price" value="${fieldValue(bean: productoProveedorInstance, field: 'price')}" required=""/>

Any suggestion will be helpful

some countries actually use commas instead of decimal points for numbers. however, see this http://stackoverflow.com/questions/6178332 — aldrin, Mar 22 '16 at 04:50

I succeeded using g:formatNumber.

<g:formatNumber number="${myNumber}" maxFractionDigits="10" locale="US" />

The locale US, forces gsp to use a decimal point. Nevertheless, without maxFractionDigits, it shows a whole number.

Use g:formatNumber instead:

<g:formatNumber number="${myNumber}" format="\\$###.##0" />

...or use pattern attribute for g:field. Here you can find an example for time format.

...or change coma for dot in selected field using javascript.

That tag `` is for displaying numbers, not formatting fields. – Douglas Mendes Nov 04 '18 at 11:54
