How do you find the floor and ceiling function?

In mathematics and computer science, the floor function is the function that takes as input a real number x, and gives as output the greatest integer less than or equal to x, denoted floor(x) or ⌊x⌋. Similarly, the ceiling function maps x to the least integer greater than or equal to x, denoted ceil(x) or ⌈x⌉.

What do the terms floor and ceiling?

The floor function of x, denoted by ⌊x⌋ or floor (x), is defined to be the greatest integer that is less than or equal to x. The ceiling function of x, denoted by ⌈x⌉ or ceil (x), is defined to be the least integer that is greater than or equal to x.

How do you find the math floor?

floor(double a) returns the largest (closest to positive infinity) double value that is less than or equal to the argument and is equal to a mathematical integer. Special cases: If the argument value is already equal to a mathematical integer, then the result is the same as the argument.

How is floor value calculated?

Divide the non-convertible bond's YTM by the number of times the convertible bond pays interest annually, and add 1. In this example, divide 4.5 percent, or 0.045, by 2 to get 0.0225. Add 1 to get 1.0225. Multiply the number of payments per year by the convertible bond's maturity length.

How do you calculate ceilings?

Multiply the length by the width to obtain the gross ceiling area. For example, a room 15 feet long and 10 feet wide has a gross ceiling area of 150 square feet -- 15 times 10 = 150.
