Standard C lacks portable string-to-float error detection

Original: No portable way to detect string-to-float conversion errors in standard C

A new write-up argues that standard C provides no portable way to detect errors when converting strings to floating-point numbers. The piece walks through the shortcomings of strtod and related functions, whose error-signalling behaviour varies across implementations. Programmers responding to the article agree it highlights a long-standing gap in the C standard library, with some suggesting platform-specific workarounds as the only real fix.

Why now: Programmers are debating a practical limitation of the C standard library affecting portable numerical parsing.
