Magic number (ARCH701)

Key dotnet.codequality.magic-number · Severity info · Category codequality

Numeric literals embedded directly in code reduce readability and hide intent. They should be replaced with named constants.

Incorrect

public decimal CalculatePrice(decimal amount)
{
    return amount * 1.18m;
}

Correct

private const decimal VatRate = 1.18m;

public decimal CalculatePrice(decimal amount)
{
    return amount * VatRate;
}

Fix

Move repeated or unclear numeric literals into a descriptively named const or static readonly field.
