The truncate() function in Ruby returns an int truncated value to a precision of ndigits decimal digits. When the precision is negative, the returned value is an integer with at least ndigits.abs trailing zeros. It returns itself when ndigits is zero or positive. The default value of ndigits is considered to be zero.
Syntax: number.truncate(ndigits)
Parameter: The function takes the integer which is to be truncated and a non-mandatory ndigits, upto which it has to be truncated.
Return Value: The function returns the truncated value to a precision of ndigits.
Example #1:
# Ruby program for truncate function # Initializing the number num1 = 120
ndigits1 = -2 num2 = 120
ndigits2 = -2 num3 = -19
ndigits3 = -1 num4 = 120
# Prints the truncated value puts num1.truncate(ndigits1) puts num2.truncate(ndigits2) puts num3.truncate(ndigits3) puts num4.truncate |
Output:
100 100 -10 120
Example #2:
# Ruby program for truncate function # Initializing the number num1 = 190
ndigits1 = -1 num2 = 10
ndigits2 = 2 num3 = 18
ndigits3 = -1 num4 = 1123
# Prints the truncated value puts num1.truncate(ndigits1) puts num2.truncate(ndigits2) puts num3.truncate(ndigits3) puts num4.truncate |
Output:
190 10 10 1123
