BigMathR

This is a math module that using the BigDecimal class. Multiple-precision arithmetic supports real and complex solutions.

It doesn't use any external libraries that have dependencies. Use only the BigDecimal class.

gem install bigdecimal-math_r

When it is called, the BigDecimal class is also called.

require 'bigdecimal/math_r'

The functions at the top level BigMathR of the module, are mathematical constants in uppercase letters, and mathematical functions in lowercase.
Mathematical functions are compatible with both real and complex solutions.

Constants:

:E (Constant e), 
:LOG2 (Natural logarithm of 2)
:LOG_PI (Natural logarithm of pi)
:LOG10 (Natural logarithm of 10)
:SQRT2 (Square root of 2)
:SQRT3 (Square root of 3)
:PI (Constant pi)

Functions:

:exp (Exponential function)
:exp2 (Base-2 (Binary) exponent)

:log (Natural logarithm)
:log2 (Binary logarithm)
:log10 (Common logarithm)
:log1p  (log(1+x))

:hypot  (Hypotenuse)

:sqrt (Square root)
