float_invert

Divide one by an XFL floating point number

Concepts

• Floating Point Numbers (XFL)

Behaviour

C

• Inverts a float representation.

• Return a inverted float as a bigint or an ErrorCode

Javascript

• Divide 1 by an XFL

• Return a new XFL as an int64_t

Definition

C

int64_t float_invert (
    int64_t float1
);

Javascript

function float_invert(f1: bigint): ErrorCode | bigint

Example

C

int64_t still_one =
    float_invert(float_one());

Javascript

const still_one =
    float_invert(float_one())

Parameters

C

Name	Type	Description
float1	int64_t	An XFL floating point enclosing number

Javascript

Name	Type	Description
f1	float	The float to invert

Return Code

C

Type	Description
int64_t	The XFL (xls17) enclosing number If negative, an error: INVALID_FLOAT - the supplied parameter was not a valid XFL enclosing number or the division resulted in an XFL that cannot be represented. DIVISION_BY_ZERO - the supplied parameter was zero.

Javascript
