Question

2. Give the output of the following statements
i) Math.ceil(22.64)
ii) Math.rint(28.98)​

Answer 1

Answer:

I) 23

ii)29

Explanation:

The following statements uses python function..second one can be easily determine using tensorflow...

Answer 2

Answer:

(i) 23.0

(i) 29.0

Note:-

Math.pow(a) returns a number raised to power other number. Return data type: Double

That's why Math.pow(22.64) =23.0 not 23

Math.rint(a)- Returns the nearest integer of a given number. Return data type: double

So it is just returns rounded value . That's why Math.rint(22.98)=29.0

• Math.pow(a) returns a number raised to power other number. Return data type: Double
• Math.ceil(a) - Rounds the number upto next higher integer. Return data type: Double
• Math.floor(a) - Rounds the number upto next lower integer. Return data type: Double.
• Math.max(a,b)- Returns the maximum value between two parameters. Return data type: Depends on the data type of the parameters.
• Math.min(a,b)- Returns minimum value between two parameters. Return data type: Depends on the data type of the parameters.
• Math.cbrt(a)- Returns cube root. Return data type: Double.
• Math.sqrt(a)- Returns square root. Return data type: Double.
• Math.log(a)- Returns natural logarithmic value of a given argument. Return data type: Double.
• Math.round(a)- Returns the number rounded to the nearest integer. (For more info: Please check the Knowledge box given at last.)
• Math.rint(a)- Returns the nearest integer of a given number. Return data type: double
• Math.exp(a)- Returns exponential value of a given argument. Return data type: double
• Math.random()- There are no argument in this function and it returns random number between 0 and 1. Return data type: double
• Math.abs(a) returns absolute (positive) value of a number. Return data type: Depends on data type input given by the user.

Knowledge Box...!

• It is necessary to know that round() and rint() are not same.
• Math.round() returns number in int data type while Math.rint() returns number in double data type.
• Another Difference... Let's take -9.5 as a parameter Math.round(-9.5) will return -9 while Math.rint(-9.5) returns -10.0
