Convert a date to string value with high precision.

String doubleToString(double value)

Convert a double to string value with high precision.

We don't want to loose internal accuracy when writing doubles but we also don't want to have ugly representations like STEP = 1.25000000000000000 so we try a few simple formats first and fall back to scientific notation if it doesn't work.

Parameters:

value - value to format

Returns:

formatted value, with all original value accuracy preserved, or null if value is null or Double.NaN

unitsListToString

String unitsListToString(List<Unit> units)

Convert a list of units to a bracketed string.

Returns:

bracketed string (null if units list is null or empty)

siToCcsdsName

String siToCcsdsName(String siName)

Convert a SI unit name to a CCSDS name.

CCSDS name for the unit
