FLT_ROUNDS

Defined in header `<float.h>`
`#define FLT_ROUNDS /* implementation defined */`

Returns the current rounding direction of floating-point arithmetic operations.

Value	Explanation
`-1`	the default rounding direction is not known
`0`	toward zero; same meaning as `FE_TOWARDZERO`
`1`	to nearest; same meaning as `FE_TONEAREST`
`2`	towards positive infinity; same meaning as `FE_UPWARD`
`3`	towards negative infinity; same meaning as `FE_DOWNWARD`
other values	implementation-defined behavior

Notes

The rounding mode can be changed with fesetround and FLT_ROUNDS reflects that change.
