'''ROUNDDOWN '''('''n''', '''ndigit''')
+
*If 'num_of_digits' is omitted, Calci displays #NaN error message.
 +
*The number is rounded down to the specified number of decimal places, if num_of_digits > 0.
 +
*The number is rounded down to the nearest integer, if num_of_digits = 0.
 +
*The number is rounded down to the left of the decimal point, if num_of_digits < 0.
 +
*If any argument is non-numeric, Calci displays #NaN error message.
   −
'''Where n''' is a number that you want rounded down and '''ndigit''' is the number of digits to which want to round the number.
+
ROUNDDOWN() can also be used for multiple number array as -
 +
 
 +
ROUNDDOWN(2.55..7.55,1) that rounds the numbers 2.55 to 6.55 to one decimal place.
