Standard C lacks portable string-to-float error detection

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

A developer argues that standard C offers no portable way to detect errors when converting strings to floating-point numbers, highlighting shortcomings in functions like strtod across platforms. The piece examines how different implementations handle invalid input and suggests the gap leaves programmers without a reliable, standards-compliant approach to error checking.

Why now: Programmers are debating long-standing limitations in the C standard library's numeric conversion functions.
