#
getPercentageBofA( $valueB, $valueA_orTotalValue, integer $percentageIs = 100 )
Parameters
- $valueB
- $valueA_orTotalValue
- $percentageIs
Returns
integer
(return only percentage B of As. e.g percetage 5 of 40 = 12.5%)

public static
integer

#
getPercentageValue( $value, integer $percentage = 10, integer $noNegativeNumber = true, boolean $percentageIs = 100 )
Parameters
- $value
- $percentage
- $noNegativeNumber
- $percentageIs
- $percentageIs
- $noNegativeNumber
Returns
integer
(return only percentage of the value passed in)
|
public static
array

#
getValueMinMaxByPercentage( $value, integer $percentage = 10, boolean $noNegativeNumber = true )
Parameters
- $value
- $percentage
- $noNegativeNumber
Returns
array
( array that consist of min, max, percentage or discount, maxFake, and value keys)
|
public static
float
|
#
getAveragePercentage( array $percentageList )
Parameters
- $percentageList
- $percentageList
Returns
float (use when you av more than one percentage to deal with);
e.g (find average percentage of 60%,40%. just convert the two number to
decimal by dividing them with 100, so u get 0.6 & 0.4, then add the two
numbers then divide the result by 2 i.e 0.5, finally multiply he result with 100)

#
toWord( $number, boolean $strictlyNumber = true )
Parameters
Returns
string If you want to convert an integer into an English word string, eg. 29 -> twenty-nine, then here's a function to do it
Note on use of fmod()
I used the floating point fmod() in preference to the % operator, because % converts the operands to int, corrupting values outside of the range [-2147483648, 2147483647]
I haven't bothered with "billion" because the word means 10e9 or 10e12 depending who you ask.
The function returns '#' if the argument does not represent a whole number.

#
isApproximatelyEqual( $number1, $number2, float $epsilon = 0.001 )
Checks if two numbers are approximately equal to each other.
Use abs() to compare the absolute difference of the two values to epsilon. Omit the third parameter, epsilon, to use a default value of 0.001.
approximatelyEqual(10.0, 10.00001); // true
approximatelyEqual(10.0, 10.01); // false
Checks if two numbers are approximately equal to each other.
