You can include the decimal option to control the number of fractional digits returned, afterrounding is performed. The decimal parameter must evaluate to an integer. For example,assume that variable c contains the number 6.25198.SET c="6.25198"SET x=$FNUMBER(c,"+",3)SET y=$FNUMBER(c,"+",8)WRITE !,x,!,yThe first $FNUMBER returns +6.252 and the second returns +6.25198000. Zero fill is performedif the decimal parameter exceeds the number of fractional digits in the number.ExamplesThe following examples show how the different formatting designations can affect thebehavior of $FNUMBER. These examples assume that the current locale is the default locale.The following example returns +124329; $FNUMBER forces a plus sign on the value of Abecause A is non-negative:SET A=124329WRITE $FNUMBER(A,"+")The following example returns 30.567; $FNUMBER removes the negative sign from thevalue of B.SET B=-30.567WRITE $FNUMBER(B,"-")The following example returns 1,234,567.81; $FNUMBER inserts a comma every 3numerals to the left of the decimal point of C.SET C=1234567.81WRITE $FNUMBER(C,",")The following example returns 1.234.567,81; $FNUMBER inserts European formatting toC.SET D=1234567.81WRITE $FNUMBER(D,".")The following example returns 124,329.00; $FNUMBER inserts a comma and adds a decimalpoint and two zeros to the value of C.SET C=124329WRITE $FNUMBER(C,",",2)$FNUMBERThe following example shows how $FNUMBER inserts the trailing character after variables:Caché ObjectScript Reference 215
