# bson_iter_overwrite_double()

## Synopsis

    void
    bson_iter_overwrite_double (bson_iter_t *iter, double value);

## Parameters

- `iter`: A bson_iter_t.
- `value`: The new double value.

## Description

The bson_iter_overwrite_double() function shall overwrite the contents of a BSON_TYPE_DOUBLE element in place.

This may only be done when the underlying bson document allows mutation.

It is a programming error to call this function when `iter` is not obvserving an element of type BSON_TYPE_DOUBLE.
