| Mar 26, 2022 at 18:34 | comment | added | pipe | By "did", you mean "still don't"? Because I use non-IEEE floats regularly and for example gcc uses them internally all the time. It's absolutely necessary when you need floating points larger than what the hardware can calculate. | |
| Mar 26, 2022 at 9:10 | comment | added | jpa | Even IEEE cannot agree on floats. IEEE-11073 is in current use and specifies a 32-bit float format that is not compatible with IEEE-754. | |

| Mar 25, 2022 at 14:04 | comment | added | Trevor Boyd Smith | i was going to say that gcc has a non-standard float128 but fortunately their documentation states that the software implementation conforms to IEEE float128 standard. unfortunately for this question i can not use the gcc float128 as an example. | |
| Mar 25, 2022 at 11:55 | comment | added | RBarryYoung | IEEE FP was a late development in the history of floating-point, it wasn't even adopted by IEEE itself until 1985 (though Intel did implement the draft version earlier). And the "Implied leading 1" trick was common to most floating point formats long before IEEE-754 (I learned it on the PDP-11 in college, circa 1975). | |
