formatPointerPercentage

public static java.lang.String formatPointerPercentage(java.math.BigInteger pointers,
                                                       java.math.BigDecimal totalPointers,
                                                       int numDecimals,
                                                       boolean addPercentPrefix)

Parameters:

pointers - the number of pointers for the current context

totalPointers - the number of pointers for all contexts

numDecimals - the number of digits to output after the decimal point.

addPercentPrefix - true if a percent sign (%) should be prefixed

Returns:

return a formatted percentage indicating the size of the analogical effect of pointers
