Read about return values of ceil function .

1st Parameter Type : double

Double-precision floating point (±1.7E±308, ~15 decimal digits)

1st Parameter

The numeric value for which the smallest integer greater than or equal to it is computed

The ceilfunction in C language Calculates the smallest integer value greater than or equal to the argument.

The ceil function computes the smallest integral value greater than or equal to x, represented as a double. In other words, it rounds x upward, returning the smallest integral value that is not less than x. This function is particularly useful when you need to round up a floating-point number to the nearest integer.

The ceilfunction takes 1 parameter:

•
double `x`: The numeric value for which the smallest integer greater than or equal to it is computed

Computes the smallest integer value greater than or equal to the given number `x` and returns it as a `double`.

The ceil function return value :

Returns the smallest integral value greater than or equal to x, expressed as a double

Output

This example demonstrates the basic usage of `ceil` with various positive and negative floating-point numbers, including zero.
