```

Code #1 : Example for **() method

 `# Ruby code for BigDecimal.**() method``   ` `# loading BigDecimal``require ``'bigdecimal'``   ` `# declaring BigDecimal``a = ``42``.``1``**``13``   ` `# declaring BigDecimal``b = -BigDecimal(``"10"``)``   ` `# declaring BigDecimal``c = -(``22` `** ``7``.``1``) ** ``10`` ` `# a raised to b``puts ``"BigDecimal a ** b : #{a**b}\n\n"`` ` `# b raised to c``puts ``"BigDecimal b ** c : #{b**c}\n\n"`` ` `# c raised to a``puts ``"BigDecimal c ** a : #{c**a}\n\n"`

Output :

```BigDecimal a ** b : 0.69715210232947426173607301244803767284033052453728372066634423193813865098214021205394462027375795972963787035593558361900700497580618199181954177853985986229377825727463990264709423242001901437761702739369196154946225636089767529806260002899406861673710067184383173593327137087471327779730396921711103521973868394159296484550564E-211
