The floor() function in Ruby is used to return the next lowest integer value (i.e. last largest integer not greaterthan the inputed value) by rounding up value if necessary.
int floor(mixed n);mixed n |
Specifies the real number (int, long, float, double) (*Required) |
|---|---|
Return mixed |
Returns a number respective to an input argument. |
Round the floating point number from 1.0 to 2.0 step by 0.1 using floor math method and print the resultant in console.
