When a GPX file is created, because of Lat and Long values being stored as doubles, they are sometimes written as exponents
EG -3.1E-4 instead of -0.00031
Not sure if there's a simple solution to this?

The data type of the latitude and longitude value is xsd:decimal.

<xsd:simpleType name="latitudeType">
    <xsd:restriction base="xsd:decimal">
    <xsd:minInclusive value="-90.0"/>
    <xsd:maxInclusive value="90.0"/>
    </xsd:restriction>
</xsd:simpleType>

The library uses the Double::toString method for converting a double value to a string, which might produce an exponential representation of the double value. So in this sense, this is a bug, which should be fixed.

Can you attach an example file with this error? And which application has problems reading these values?

test42.gpx.txt

GPX file attached (added .txt for GitHub to accept).

Only applications I've tried it with are Basecamp and Viewranger - both fail to parse the file, and don't import anything.
I've manually altered the gpx to correct the exponent to a number, and then they are happy and parse the file.
