BC Mobile is an arbitrary precision scientific calculator based on GNU bc which is a language that supports arbitrary precision numbers with interactive execution of statements. It supports a standard math library and variable base like hex, octal, decimal and binary.
A preloaded math library defines the following functions and constant:
s(x) : The sine of x
c(x) : The cosine of x
a(x) : The arctangent of x
l(x) : The natural logarithm of x
e(x) : The expornential function of raising e to the value x
j(n,x) : The bessel function of integer order n of x
pi : The value of PI (scale = 100)
