PRC( ) |
Round Number to Precision |
PRC(num[,precision][,ERR=stmtref])
Where:
|
num |
Value to be rounded. Numeric expression. |
|
precision |
Precision to which to round. Optional. Numeric expression. Integer from 0 to 18. If omitted, rounding is done to the current precision in effect. |
|
stmtref |
Program line number or statement label to which to transfer control. |
Numeric value, rounded to a set precision.
The PRC( ) function returns a given numeric value (num) rounded to the set precision.
If a precision parameter is supplied, the PRC( ) function rounds the value based on the new precision. If precision is not supplied, then the value is rounded to the current PRECISION in effect.
If you use an invalid value (e.g. >18), PxPlus returns Error #41: Invalid integer encountered (range error or non-integer).
