sdlGetFloatProperty function properties

double sdlGetFloatProperty(int props, String? name, double defaultValue)

Get a floating point property from a group of properties.

You can use SDL_GetPropertyType() to query whether the property exists and is a floating point property.

\param props the properties to query. \param name the name of the property to query. \param default_value the default value of the property. \returns the value of the property, or default_value if it is not set or not a float property.

\threadsafety It is safe to call this function from any thread.

\since This function is available since SDL 3.2.0.
