Standard C offers no portable way to detect string-to-float errors
Original: oh, apparently it's not possible to portably check for string-to-float conversion errors in standard c https://sebsite.p
A write-up argues that standard C provides no portable method for detecting string-to-float conversion errors with strtod. The claim is drawing attention among C programmers on developer forums, where the inability to reliably distinguish conversion failures from valid conversions like 0.0 is being discussed as a persistent flaw in the standard library's design.
Why now: Programmers are debating a longstanding, practical flaw in the C standard library that affects everyday numeric parsing code.
