Go language provides inbuilt support for basic constants and mathematical functions to perform operations on the numbers with the help of the math package. You are allowed to find the least integer value greater than or equal to the specified number with the help of the Ceil() function provided by the math package. So, you need to add a math package in your program with the help of the import keyword to access the Ceil() function.
func Ceil(y float64) float64
- If you pass +Inf or -Inf in this function, then this function will return +Inf or -Inf.
- If you pass -0 or +0 in this function, then this function will return -0 or +0.
- If you pass NaN in this function, then this function will return NaN.
Result 1: 2.0 Result 2: 35.0 Result 3: -12.0
0.7 + 0.5 = 1.2 Round off result: 2
