Remarks

MS-VBAL §6.1.2.10.1.1 (Abs), §6.1.2.3.1.16 (Fix) and §6.1.2.3.1.18 (Int) declare each As Variant, which returns "a value of the same value type" as a number it is given. MS-VBA types the call itself as its argument's declared type when that is a numeric type: Fix(n) of an Integer is an Integer, and Fix(n) * 7000 is a product of Integers, which overflows (error 6) where a Variant product would be a Long (recorded in Excel: oracle\s46 F10, as vb6.exe does). RD-VBA types the call as MS-VBA does, and warns where the difference shows.

An argument of any other declared type - a Variant, a String, a Boolean, a Date - leaves the call a Variant, as declared.

Methods

DeclaredTypeOfCall(Symbol, VBType?)

The declared type of a call of procedure given an argument of argumentType, when it is not the one procedure declares: the argument's, for Abs, Int or Fix of a numeric value.

procedure Symbol

argumentType VBType

The declared type of its one argument, if it is known.

Returns

VBType

The type; null when the call is of the type procedure declares.

IsTypedByItsArgument(Symbol)

Whether procedure is the standard library's Abs, Int or Fix, whose call is of its argument's numeric type.

public static bool IsTypedByItsArgument(Symbol procedure)

Parameters

procedure Symbol

The procedure.

Returns

bool
