'''bc''', for ''basic calculator'', is "an [[Arbitrary-precision arithmetic|arbitrary-precision]] [[math]]ematical [[calculator]] language"[[computer program|program]] with syntaxan input language similar to the [[C (programming language)|C programming language]]. bcIt issupports typicallyboth usedinteractive, as[[command-line eitherinterface|command-line]] a mathematical scripting language[[user-interface]] or as an interactiveand mathematicalscript shellprocessing.

==Overview==

Line 37:

All numbers and variable contents are [[arbitrary-precision]] numbers whose precision (in decimal places) is determined by the global '''<code>scale</code>''' variable.

The [[base (exponentiation)radix|numeric base]] of input (in interactive mode), output and program constants may be specified by setting the reserved '''<code>ibase</code>''' (input base) and '''<code>obase</code>''' (output base) variables.

Output is generated by deliberately not assigning the result of a calculation to a variable.
