# Standard Form Calculator

Enter a number in the box and it will be displayed in *significand* and *exponent* form (i.e. a number and a power of ten). This is commonly known as standard form or scientific notation, and is ideal for students of GCSE Maths or Science.

The arrows can be used to shift the position of the decimal point and adjust the power of ten by a corresponding amount. How many places do you need to shift the digits to get the number into *standard form*? If you click the *Standard Form* button, the page will do it for you - but can you see where the numbers come from? NB. Rounding errors are common in JavaScript, so the result is rounded to (at most) twenty decimal places.
