package to encpasulate float64 in protobuf

I was working in a microservice to create subscriptions in Stripe. One of the fields is listed as a float64 where I set it up as a float in the .proto file. This cast the field as a float32 not float64.

I cannot see a direct way to make protobuf to produce a file with the field typed as float64. Can someone help me here? Is there any special package for protobuf that encapsulates a float64?

Many Thanks

>Solution :

As mentioned in Scalar Value Types, float64 in Go is defined with double in protobuf. So instead of writing:

float a_field = 1;

you will write:

double a_field = 1;
