Module Fit.DecodeSource

values reported as part of a record are often encoded or scaled. This module provides typical decoders. How values are decoded depends on the field and the information is not part of the FIT file per se but is part of the format definition.

Sourceval timestamp : value -> float

decode a time-stamp field; it expects an Int value

Sourceval scale : int -> int -> value -> float

many values are scaled. The scale consists of an offset and a factor: scale factor offset value decodes value using factor and offset. The value is expected to be an Int or Float value.

Sourceval latlon : value -> float

Coordinates in latitude or longitude are decoded using latlon. The value is expected to be an Int.
