Java Math.ceil - Syntax
mixed ceil(mixed n);Java Math.ceil library function
The Math.ceil() function in Java is used to return the next highest integer value by rounding up value if necessary.
Java Math.ceil - Parameter and Retun type
mixed n |
Specifies the real number (int, long, float, double) / infinity (*Required) |
|---|---|
Return mixed |
Returns a number / infinity respective to an input argument. |
Example: #1 - Java Math.ceil
Round the floating point number from 1.0 to 2.0 step by 0.1 using ceiling math method and print the resultant in console.
