Enumerations
enum	TArithmetic {   ADD , SUB , MULT , DIV ,   DIST }
	Mathematical operators (+, -, *, /) and functions (round, degrees, ...) for temporal numbers. More...

Functions
Temporal *	arithop_tnumber_number (const Temporal *temp, Datum value, TArithmetic oper, Datum(*func)(Datum, Datum, meosType), bool invert)
	Generic arithmetic operator on a temporal number and a number. More...
Temporal *	arithop_tnumber_tnumber (const Temporal *temp1, const Temporal *temp2, TArithmetic oper, Datum(*func)(Datum, Datum, meosType), tpfunc_temp tpfunc)
	Generic arithmetic operator on two temporal numbers. More...
int	tfloat_arithop_turnpt (Datum start1, Datum end1, Datum start2, Datum end2, Datum param UNUSED, TimestampTz lower, TimestampTz upper, TimestampTz *t1, TimestampTz *t2)
	Find the single timestamptz at which the operation of two temporal float segments is at a local minimum/maximum. More...
