123 ('99.99999') -> #numberFormat(123.12,'99.99999')#<br/>
</cfoutput>

<cfoutput>
123 ('_____') -> #numberFormat(123,'_____')#<br/>
123 ('_.___') -> #numberFormat(123,'_.___')#<br/>

</cfoutput>

numberFormat(1.23,'__.00')

Expected Result: 1.23

numberFormat(123,'__.00')

Expected Result: 123.00

num1 = NumberFormat(123,'00000');
num2 = NumberFormat(123,'99999');
    
writeOutput(num1&'/'&num2);

Expected Result: 00123/ 123

num1 = NumberFormat( 5, "+" );
num2 = NumberFormat( -5, "+" );
    
writeOutput(num1&'/'&num2);

Expected Result: +5/-5
