Translates a double into a BigDecimal , using the double 's canonical string representation provided by the Double#toString(double) method.

Usage

From source file:com.sarm.calculatepi.calculator.PiCalculatorImpl.java

/**
 * This method calculates the Pi using the Leibniz formula.

    //        get Pi
