Synopsis
`PRECISION int`
Arguments
 int An integer specifying the maximum number of decimal digits.
Description
The PRECISION statement specifies the maximum number of decimal digits to display when converting a floating point number. It rounds the decimal portion to the number of decimal digits specified in int. The default number of decimal digits is 4.
PRECISION does not add trailing zeros to numbers with fewer decimal digits than specified.
If int is 0, the null string, or a non-numeric string, PRECISION rounds all decimal digits to the nearest integer value.
Examples
The following example illustrates use of the PRECISION statement to provide a precision value to the FIX function:
```mynum=123.987654321
PRINT FIX(mynum)
! returns 123.9877
! (rounds to the default precision of 4)
PRECISION 2
PRINT FIX(mynum)
! returns 123.99
! (rounds to a precision of 2)
