Why is this an issue?
From Delphi 11 onwards, digit separators _ can be used to split numeric literals into
  groups.

  To improve readability, this rule verifies that numeric literals above a configurable size
  in digits use separators.


Noncompliant code example
  const
    DecimalInt     = 10000;      // Noncompliant; more than 4 digits without separators
    HexadecimalInt = $7FFFF;     // Noncompliant; more than 4 digits without separators
    BinaryInt      = %01010;     // Noncompliant; more than 4 digits without separators
    Float          = 10000.0;    // Noncompliant; more than 4 (integer) digits without separators


Compliant code example
  const
    DecimalInt       = 10_000;
    HexadecimalInt   = $7_FFFF;
    BinaryInt        = %0_10_10;
    LongDecimalFloat = 10_000.0;
    FloatWithAnySeps = 10.0_0_00_1;
    FloatWithoutSeps = 10.00001;


Exceptions

  Only the integer component of floating point numbers is checked for compliance; the fractional and
  exponent parts are ignored.


How to fix it

  Group the digits in the number using _ between groups.
