*The usual disclaimers apply. May not always be accurate. Please remember that 1 million digit precision will result in 1 megabyte of output, which could take several minutes to download into your browser!

Supports number base conversion or encryption up to base 256 (but some browsers are only capable of displaying base 128).  Converting to / from base 64 is not the same as base64 mail attachment (mime) format. For that, use base64 encode/decode

Update:  Now accepts functions and expressions like 3*sin(45/5e4) when calculating in base 10.  Be aware that accuracy is limited on formulas entered in this way.
