Subtraction operator (LotusScript Language)

Finds the difference between two numbers.

Syntax

numExpr1 - numExpr2

Elements

numExpr1, numExpr2

Any numeric constant, variable, or expression; or any function that returns a number. An EMPTY operand is considered a 0.

Return value

The result is a value whose data type is generally the same as that of the operand whose data type is latest in this ordering: Integer, Long, Single, Double, Currency. For example, if one operand is a Long and the other is a Currency, then the data type of the result is Currency.

The exceptions are:

  • When the result is a Variant of Integer that overflows its legal range, the result is converted to a Variant of Long.
  • When the result is a Variant of Long, Single, or Date/Time that overflows its legal range, the result is converted to a Variant of Double.
  • If numExpr1 and numExpr2 are both EMPTY, the result has Integer.
  • If either or both operands are NULL expressions, the result is a NULL.
  • If numExpr1 and numExpr2 are both Variants of date/time values, the result is a Variant of Double.
