So you can replace that in Python with a shorthand of 1e09. It lets you replace powers of ten with e or E.Īs you may know, a billion is 10 9. This is where the exponent notation helps. The exponent notation becomes handy with numbers that have a lot of digits.įor example, a big number like one billion ( 1 000 000 000) can be hard to read in Python.
#Large power of ten how to#
Now that you know how to raise numbers to powers in Python, it’s time to learn what the exponent notation means in Python. Python Exponent Notation-Get Rid of Zeros If you are a beginner, it does not really matter which approach you use as long as it works. The pow was 104.58659450456607 times fasterĪll in all, the differences between pow(), math.pow(), and ** are subtle but they exist. Math_pow_time = timeit('math.pow(70, i)', setup='import math i = 10') This is because it does not involve a separate function call.Īsterisk_time = timeit('70. The double-asterisk approach is slightly faster than pow() or math.pow(). Let’s go through each of these main differences in a bit more detail. The built-in pow() function accepts a third argument.Math.pow() does not allow imaginary numbers.But there are some slight differences you may be interested to learn.
Let’s discuss the differences between them.Īll three approaches work almost identically with one another. There are three main ways to raise a number to a power in Python. This function does the same thing as the two earlier power calculating approaches. Just remember to import the math module into your project. Math.pow() Functionįinally, you may also use math.pow() function to raise a number to a power. You can also use the built-in pow() function to raise a number to a power.įor instance: pow(2, 3) # -> 8 3. Most of the time, this approach is the fastest to compute power in Python. This is a clear and efficient way to compute powers in Python. You can use the double-asterisk operator to raise a number to a power in Python. We are also going to discuss the subtle differences between these methods. Let’s go through each of these with examples. There are three ways you can raise a number to a power in Python: How to Raise a Number to a Power in Python Let’s also get to know the exponent notation, which can help you represent large and small numbers. Let’s see how to calculate exponents in Python. This means number 2 is multiplied by itself 3 times. The operation involving exponents is called raising a number to a power. In maths, the exponent is denoted with a number as a superscript, such as 2 3. Python Exponent Notation-Get Rid of ZerosĪn exponent is the number of times the number is multiplied by itself.Math.pow() Does Not Accept Imaginary Numbers How to Raise a Number to a Power in Python.
