Oracletrunc () function usage-2
2. TRUNC (for number)
The TRUNC function returns the processed value. Its working mechanism is very similar to that of the ROUND function, except that the function does not ROUND or select the part before or after the specified decimal number.
The syntax format is as follows:
TRUNC (number [, decimals])
Where:
Number the value to be intercepted
Decimals indicates the number of digits after the decimal point to be retained. Optional. If this parameter is ignored, all decimal parts are truncated.
The usage of this function is as follows:
TRUNC (89.985, 2) = 89.98
