The Copasetic Flow Google Gadget Scientific Calculator

The Copasetic Flow Scientific Calculator was built using the Google Gadget API and is used on many pages around the site, like the ham radio exams:

Technician Class USA
General Class USA
Extra Class USA
Basic Canada

If you'd like to add it to your site or igoogle page, go here.

The Copasetic Flow scientific calculator works exactly like you'd expect a calculator to. You'll notice a few extra buttons if you haven't used a scientific calculator before. Here's what they're for.

Raise x to the yth power. First, enter the number for x, for example two. Then, click the x^y button and enter the number for y, for example three. When you press =, you'll get 2 raised to the third power, (2 times 2 times 2): 8.

Raise the number e, (Euler's constant, 2.718...), to the power shown on the screen. Enter the number for x, for example two. When you press the e^x button, you'll get the answer for e raised to the second power: 7.389.

Raise ten to the power shown on the screen. Enter the number for x, for example two. When you press the 10^x button, you'll get the answer for ten raised to the second power: 100.

When you enter a number and press the 'ln' button, the answer returned will be the natural logarithm of the number you entered. The logarithm of 0 is negative infinity, so, if you enter 0, the result will be 'Err'.

When you enter a number and press the 'log' button, the answer returned will be the logarithm base 10 of the number you entered. The logarithm of 0 is negative infinity, so, if you enter 0, the result will be 'Err'.

This button returns the inverse of the number on the screen, (one divided by the number on the screen.) For example, entereing a 2 and pressing this button will return the answer 0.5.
