print(math.floor(0.5))
print(math.floor(9.9))The math.floor() function returns the floor value of a real number, which is the largest integer less than or equal to the number. For example, the floor value of 4.7 is 4, because 4 is the largest integer less than or equal to 4.7. Similarly, the floor value of -3.2 is -4, because -4 is the largest integer less than or equal to -3.2.
math.floor(x)x |
The number whose floor value is to be determined. It can be any valid real number i.e a floating point value or an integer. |
The function returns the floor value of x. If x is an integer the return value is just as same as x.
