MinIntValue

function MinIntValue(const aValues: array of Integer): Integer;

Example​

procedure ScriptEvent(var Value: variant);
begin
  Value := MinIntValue([4, -2, 9, -2]); // -2
end;

Usage​

MinIntValue returns the smallest Integer in a non-empty open-array argument.

Parameters

NameTypeDescription
aValuesopen array of Integer, constOne or more 32-bit signed values. Inline open-array syntax such as [A, B, C] is supported.

Returns

The least element. Duplicate minima do not change the result and no index is returned.

Additional Technical Info​

MinIntValue returns the smallest actual value in a non-empty open array of 32-bit Integers. It does not return the minimum representable Integer type constant; use Low for a type/storage boundary.

The wrapper delegates directly to Delphi System.Math.MinIntValue. The example is fictional and source-reviewed only.

Implementation

The Velox wrapper calls Math.MinIntValue(aValues). The installed RTL initializes the result from Data[Low(Data)], then linearly replaces it whenever a smaller value is found.

Edge cases and errors

  • An empty array is invalid. The installed RTL immediately reads Data[0] without first checking the length. That access is inside the separately compiled RTL, so the product project's range-check setting does not make the result predictably safe: an RTL build with checks can raise ERangeError; otherwise the call can read outside the empty array and return an undefined value. Never pass an empty array.
  • A single element returns itself.
  • Values remain exact 32-bit Integers; there is no floating conversion or locale behavior.
  • Element-expression conversion/evaluation errors occur before the helper is entered.

Performance and side effects

The function is pure and performs a linear O(n) scan with constant additional storage. It does not sort or mutate the array.

  • Low returns an index or type minimum rather than an array value minimum.
