- Compute an XFL (xls17) floating point from the provided exponent and mantissa
- Return that XFL as an int64_t
int64_t float_set ( int32_t exponent, int64_t mantissa );
int64_t small_amount = float_set(-81, 1);
|exponent||int32_t||An exponent in the range |
|mantissa||int64_t||A mantissa. If negative then the sign of the float is negative.|
When setting a mantissa that is greater or fewer than 16 decimal digits the exponent will be adjusted to ensure the mantissa is exactly 16 digits. This adjustment may result in an
INVALID_FLOATin some circumstances.
XFL canonical 0 is also 0 in the enclosing number. Thus there is never a need to call
|int64_t||The XFL (xls17) enclosing number|
If negative, an error:
- The adjustment of the mantissa to 16 digits produced an under or overflow.
