C++ Math trunc()
The function rounds off the given value towards zero and returns the nearest integral value whose magnitude is not greater than the given value.
Suppose a number is 'x'. Syntax would be :
Note: return_type can be float,double or long double.
x: The value that can be float,double or long double.
It returns a rounded value of x.
Let's see a simple example when the value of x is positive.
The value of x is :8.8 Truncated value of x is :8
Let's see a simple example when the value of x is negative.
The value of x is :-3.9 Truncated value of x is:-3
