Multiply two XFL numbers together

Concepts

Behaviour

  • Compute the multiplication of two XFL (xls17) floating point numbers
  • Return a new XFL as an int64_t

Definition

int64_t float_multiply (
    int64_t float1,
    int64_t float2
);

Example

int64_t max_vault_pusd =
    float_multiply(vault_xrp, exchange_rate);

Parameters

NameTypeDescription
float1int64_tAn XFL floating point enclosing number representing the first operand to the multiplication
float2int64_tAn XFL floating point enclosing number representing the second operand to the multiplication

🚧

Caution

Certain multiplications may overflow, which return with an INVALID_FLOAT error. However an underflow returns as XFL Canonical Zero (i.e. enclosing number = 0).

Return Code

TypeDescription
int64_tThe 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 multiplication was too large to store in an XFL.
