Here sin and pi are referred to with a shortened library name m instead of math. Library call 3 does exactly that using theimport … Syntax – it creates an alias for math in the form of the shortened name m.

The main reason not to use this form of import is to avoid name clashes. For instance, you wouldn’t import degrees this way if you also wanted to use the name degrees for a variable or function of your own. Or if you were to also import a function named degrees from another library. Here sin and pi are referred to with the regular library name math, so the regular import …

You can substitute values to the equation to calculate the remaining quantity of any radioactive substance. When you use decimal values, the return type changes to a decimal value. You can see from the above examples that nan is not close to any value, not even to itself. On the other hand, inf is not close to any numerical values, not even to very large ones, but it is close to itself. With trunc(), negative numbers are always rounded upward toward zero and positive numbers are always rounded downward toward zero. You can’t give non-number values as input to ceil().

As you can see, you can’t input a negative value to log(). This is because log values are undefined for negative numbers and zero. Pow() raises the base to the power , and then the result value is modulo divided by the modulus number . You can substitute your own values and see that both pow() and the given equation provide the same results.

Return the non-negative square-root of an array, element-wise. Decompose the elements of x into mantissa and twos exponent. Logarithm of the sum of exponentiations of the inputs in base-2.
