nextpow
nextpow(a, x)
The smallest a^n not less than x, where n is a non-negative integer. a must be greater than 1, and x must be greater than 0.
Examples
julia> nextpow(2, 10)
4In this example, the function nextpow returns the smallest power of 2 (a) that is not less than 10 (x). The output is 4, as 2 raised to the power of 4 is 16, which is greater than 10.
julia> nextpow(3, 50)
4Here, the function nextpow calculates the smallest power of 3 (a) that is not less than 50 (x). The output is 4, as 3 raised to the power of 4 is 81, which is greater than 50.
julia> nextpow(10, 1000)
3In this example, the function nextpow determines the smallest power of 10 (a) that is not less than 1000 (x). The output is 3, as 10 raised to the power of 3 is 1000, which is equal to 1000.
Common mistake example:
julia> nextpow(0, 5)
ERROR: DomainError with 0.0:
Argument 0.0 to exponentiate must be greater than zeroThis example shows an error that occurs when the value of a is less than or equal to 1. The a value must be greater than 1 for the nextpow function to work correctly.
