=======================
SYNTAX prec( DATA ARRAY, PRECISION )
FUNCTION Truncates DATA ARRAY to PRECISION decimal places.
EXAMPLE The formula "prec( 10.12981, 2 )" returns 10.120. The formula "prec( 10.12981, 4 )" returns 10.12980. Small binary rounding errors may cause some minor distortion in the decimal portion of any number stored in a computer.

Unfortunately MetaStock will always display all decimal places in
indicator and exploration values. There is a way to restrict decimal
place output only in the Expert Commentary.
The best solution is to round-off decimal places.
Try this indicator example from
http://www.metastocktools.com/#metastock :
===================================
Round to nearest decimal or integer
===================================

{ Rounds off data array to nearest specified
decimal place [+x] or integer [-x].

{ Sample Data Array to be rounded }
val:=Mov(C,21,E);
{ User inputs }
x:=Input("Round to nearest decimal [+x] or integer [-x]",-10,10,1);
plot:=Input("Data output: [1]Rounded, [2]Original",1,2,1);
{ Rounding engine }
rounded:=Int(val*Exp(Log(10)*Int(x))+.5)
/Exp(Log(10)*Int(x));
{ Plot in own window }
If(plot=1,rounded,val)
