1e-8 and 1e-08 difference reported as a breaking change #207
Description
When comparing OpenAPI specs that contain floating-point defaults like 1e-08, openapi-changes reports a change if the compared value is1e-8. This is a cosmetic difference only – both are numerically identical JSON values and should not be considered a change.
To Reproduce
Save the following as openapi1.json:
{
"openapi": "3.0.0",
"info": {
"title": "Example",
"version": "1.0.0"
},
"paths": {},
"components": {
"schemas": {
"Config": {
"type": "object",
"properties": {
"angle_threshold": {
"type": "number",
"exclusiveMinimum": 0.0,
"title": "Angle Threshold",
"default": 1e-08
}
}
}
}
}
}
Save the following as openapi2.json:
{
"openapi": "3.0.0",
"info": {
"title": "Example",
"version": "1.0.0"
},
"paths": {},
"components": {
"schemas": {
"Config": {
"type": "object",
"properties": {
"angle_threshold": {
"type": "number",
"exclusiveMinimum": 0.0,
"title": "Angle Threshold",
"default": 1e-8
}
}
}
}
}
}
