Validation for latitude and longitude values using ng-pattern

Question

I have used ng-pattern

/^[0-9]{1,7}(\.[0-9]+)?$/

for validate latitude and longitude values, but this pattern is not allowing me to enter negative values.

Latitude and longitude values contains negative and decimal values Can you please suggest me one good ng-pattern for my requirements.

Example values are given below

234.546655, 3.5766876, 12345.766566

I need validation for this type values. It should allow negative,positive,decimal and all numbers

For your example: [-+]? is required for either - or +

/^[-+]?[0-9]{1,7}(\.[0-9]+)?$/
