The DecimalEdit component is a single-line editor of high-precision real numbers.
The DecimalEdit component is identical to the FloatEdit component and is used to edit real numbers. Unlike FloatEdit, DecimalEdit enables the user to edit high-precision numbers up to 18 decimal places after the point. Precision is set in the Precision property. The step, by which the value is changed on pressing the UP or DOWN keys or buttons in the SPINUP/SPINDOWN component, is set in the StepSize property.
