Return type  Name and parameters 

void

downto(Number to, Closure closure)
Iterates from this number down to the given number, inclusive, decrementing by one each time. 
Number

multiply(Double right)
Multiply a BigDecimal and a Double. 
Number

multiply(BigInteger right)
Multiply a BigDecimal and a BigInteger. 
Number

power(Integer exponent)
Power of a BigDecimal to an integer certain exponent. 
BigDecimal

round()
Round the value Note that this method differs from BigDecimal#round(java.math.MathContext) which specifies the digits to retain starting from the leftmost nonzero digit. 
BigDecimal

round(int precision)
Round the value Note that this method differs from BigDecimal#round(java.math.MathContext) which specifies the digits to retain starting from the leftmost nonzero digit. 
BigDecimal

trunc()
Truncate the value 
BigDecimal

trunc(int precision)
Truncate the value 
void

upto(Number to, Closure closure)
Iterates from this number up to the given number, inclusive, incrementing by one each time.

Iterates from this number down to the given number, inclusive, decrementing by one each time. Each number is passed to the closure. Example:
10.5.downto(0) { println it }Prints numbers 10.5, 9.5 ... to 0.5.

 the code to execute for each numberMultiply a BigDecimal and a Double. Note: This method was added to enforce the Groovy rule of BigDecimal*Double == Double. Without this method, the multiply(BigDecimal) method in BigDecimal would respond and return a BigDecimal instead. Since BigDecimal is preferred over Number, the Number*Number method is not chosen as in older versions of Groovy.

 a DoubleMultiply a BigDecimal and a BigInteger. Note: This method was added to enforce the Groovy rule of BigDecimal*long == long. Without this method, the multiply(BigDecimal) method in BigDecimal would respond and return a BigDecimal instead. Since BigDecimal is preferred over Number, the Number*Number method is not chosen as in older versions of Groovy. BigInteger is the fallback for all integer types in Groovy
right
 a BigIntegerPower of a BigDecimal to an integer certain exponent. If the exponent is positive, call the BigDecimal.pow(int) method to maintain precision. Called by the '**' operator.
exponent
 an Integer exponentRound the value
Note that this method differs from BigDecimal#round(java.math.MathContext) which specifies the digits to retain starting from the leftmost nonzero digit. This methods rounds the integral part to the nearest whole number.
Round the value
Note that this method differs from BigDecimal#round(java.math.MathContext) which specifies the digits to retain starting from the leftmost nonzero digit. This method operates on the fractional part of the number and the precision argument specifies the number of digits to the right of the decimal point to retain.
