float_sum

Add two XFL numbers together

Concepts

• Floating Point Numbers (XFL)

Behaviour

• Compute the addition of two XFL (xls17) floating point numbers

• Return a new XFL as an int64_t

Definition

C

int64_t float_sum (
    int64_t float1,
    int64_t float2
);

Example

C

int64_t two =
    float_sum(float_one(), float_one());

Parameters

Name	Type	Description
float1	int64_t	An XFL floating point enclosing number representing the first operand to the addition
float2	int64_t	An XFL floating point enclosing number representing the second operand to the addition

📘Hint

To subtract two floats use float_negate on the second float then use float_sum.

Return Code

Type	Description
int64_t	The XFL (xls17) enclosing number If negative, an error: INVALID_FLOAT - one of the supplied parameters was not a valid XFL enclosing number OVERFLOW - the result of the addition was too large to store in an XFL.
