The radix, also known as its base, indicates the amount of unique digits used to express a number. The most commonly used radix is 10, also known as the decimal system, since it uses 10 digits, from 0 to 9.
CalcBot supports radix inputs from base 2 to 64. See the calculate reference to see how to use them.
A symbol is essentially a fancy name for variable. Symbol names in CalcBot can only consist of letters and underscores. The word is occasionally used in place of the other and vice versa.
Truthiness refers to whether or not a value should be considered true or false. In CalcBot, all values are automatically considered true, except for zero (and any vector whose components are zero), which is considered false.
Examples of truthy expressions and values include 3i, 0+1, sin(pi/2).
