float_multiply

Multiply two XFL numbers together

Last updated 2 months ago

Was this helpful?

Concepts

Behaviour

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

  • Return a new XFL as an int64_t

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

  • Return n error code or new XFL as a bigint.

Definition

int64_t float_multiply (
    int64_t float1,
    int64_t float2
);

function float_multiply(f1: bigint, f2: bigint): ErrorCode | bigint

Example

int64_t max_vault_pusd =
    float_multiply(vault_xrp, exchange_rate);

const max_vault_pusd =
    float_multiply(vault_xrp, exchange_rate)

Parameters

Name
Type
Description

float1

int64_t

An XFL floating point enclosing number representing the first operand to the multiplication

float2

int64_t

An 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).

Name
Type
Description

f1

bigint

An XFL floating point enclosing number representing the first operand to the multiplication

f2

bigint

An XFL floating point enclosing number representing the second operand to the multiplication

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 multiplication was too large to store in an XFL.

Type
Description

Errorcor or bigint

An error code or The XFL (xls17) enclosing number
