DROUND

The DROUND function performs double-precision rounding on a value. Double-precision rounding uses two words to store a number, accommodating a larger number than in single-precision rounding, which stores each number in a single word.

COMMAND SYNTAX

    DROUND(val.expr [,precision.expr])

NOTE: DROUND affects the internal representation of the numeric value. It performs the rounding without conversion to and from string variables. This increases the speed of calculation.

SYNTAX ELEMENTS

val.expr specifies the value to round.

precision.expr specifies the precision for the rounding. Default precision is four places.

EXAMPLE

       V.PI = 3.14159265358979323846
       CRT 'Default:', DROUND(V.PI)
       FOR V.I = 0 TO 20
          CRT DROUND(V.PI, V.I)
       NEXT V.I

Output:

     Default:	3.1416
     3
