bs_decimalAllowed
Is the potential number allowed to be a decimal? If 'true', then yes. If 'false', no.
RETURNS
true
If s_potentialNumber is a legal integer (regardless the value of bs_decimalAllowed). A legal integer is a string that...
...contains one or more zeros. Note that 0 equals 0000 equals 0000000000 equals ...
...starts with zero or one dashes (indicating negative), followed by one or more digits (0-9), where at least one is greater than zero.
If bs_decimalAllowed is 'true' and s_potentialNumber is a legal decimal. A legal decimal is a string that...
...is an integer.
...starts with zero or one dashes (indicating negative) followed by zero or more digits, followed by a decimal point ('.'), followed by *one* or more digits.
(Note that s_potentialNumber is checked to be an integer first. If it is, then true is returned, regardless the value of bs_decimalAllowed. If the string is an integer, it is not checked, specifically, to see if it's a decimal. Hence, the description of a legal decimal number says "a decimal point" instead of "zero or one decimal points".)

/**
Is the provided string (who's value is a non-negative integer) legal?
PARAMETERS
s_potentialInt
The string to analyze. Required, and it is *assumed* that this only contains digits (0-9. Decimal points ['.'] and negative symbols ['-'] are not legal). If it contains anything else, this function will behave unpredictably.
bs_trailingZeroOk
Required. Must equal "true" or "false". If "true", then s_potentialInt is considered legal if it starts with one or more zeros (regardless if it actually equals zero). If "false", then when s_potentialInt starts with a zero, this function returns false. This parameter is primary, over bs_zeroOk (see "NOTE").
bs_zeroOk
Required. Must equal "true" or "false". If "true", then s_potentialInt is considered legal if it is equal to zero ("0", "00", "00000", "0000000000", ...). If "false", then when s_potentialInt equals zero, this function returns false. No matter what, a non-zero value is okay, even if there are trailing zeros (however, this does not override bs_trailingZeroOk). This parameter is secondary to bs_trailingZerosOk (see "NOTE").
NOTE.
Note which combinations of bs_trailingZeroOk and bs_zeroOk are legal:
bs_trailingZeroOk bs_zeroOk LEGAL?
true true yes
true false yes
false true NO
false false yes
RETURNS
true
If s_potentialInt conforms to the rules defined by bs_zeroOk and bs_trailingZeroOk parameters.
false
If otherwise.
