Text Time Text "Metrohm" + Time(1999;10;7) =
"Metrohm1999-10-07 00:00:00
UTC+2" Before the operation, the operand
of the Date/Time type is con-
verted to Text.

both operands of the same type:
Number Number Number 1.2 – 3 = –1.8 –
Text Text Text "Metrohm" – "AG" = invalid This operation is not allowed.
Time Time Number Time(1998;01;06) –
Time(1964;12;03) = 12,087.00 (for
UTC+1) Result: Number of days calculated
from December 1899, dependent
on the system time
Operands of a different type: The operand which does not correspond to the result type is converted to the rele-
vant result type before the operation.
