MathUtil::Decimal Class

Discussion

When doing numeric calculations with Xbasic there can sometimes be a loss of precision because internally Xbasic uses floating point numbers. The MathUtil::Decimal class can be used for high precision calculations. When using this class, all input numbers and output results are variables of type character (not number).

For example:

Example

? MathUtil::Decimal::Add("1.20","2.30")
= "3.50"
? MathUtil::Decimal::Subtract("1.20","2.30")
= "-1.10"
? MathUtil::Decimal::Multiply("1.20","2.30")
= "2.7600"

? MathUtil::Decimal::Divide("1.20","2.30")
= "0.5217391304347826086956521739"

? MathUtil::Decimal::Compare("1.20","2.30")
= -1

Methods

Add Method: Adds two numbers (defined as character strings) together.
Ceiling Method: Computes the ceiling of the value.
Compare Method: Compares two values. Returns 0 if they are equal, 1 if the second value is greater, -1 if the first value is greater.
Divide Method: Divides two specified values.
Floor Method: Rounds a specified number to the closest integer toward negative infinity.
Multiply Method: Multiplies two values together.
Negate Method: Negates the value.
Remainder Method: Computes the remainder after dividing two values.
Round Method: Rounds the value to the nearest integer or specified number of decimal places.
Subtract Method: Subtracts one value from another.
