| Feb 7, 2019 at 20:26 | comment | added | John R. Strohm | Both FORTRAN II and FORTRAN IV had intrinsics: in-line functions. Mixed-mode expressions were accepted by every FORTRAN IV compiler I ever used. (I learned FORTRAN II initially, but never used it. I used FORTRAN IV starting in 1970, on the CDC 6600 at UT Austin.) Programmers were warned that mixed-mode expressions could have interesting results. | |
| Feb 7, 2019 at 1:14 | comment | added | dave | Further: per the manual linked by @FelixPalmen in his answer, the first 704 Fortran had intrinsics - although the term doesn't appear, they are built-in open subroutines, i.e,, intrinsics. The relevant ones here are ABSF and XINTF. | |
| Feb 6, 2019 at 14:58 | comment | added | Raffzahn | @another-dave You're right. FORTRAN II did convert on expression assignemnts. I added that as a footnote. | |
| Feb 6, 2019 at 0:15 | comment | added | dave | I agree with @FelixPalmen in that the posed question is not about type conversions, though type conversions are mentioned in the middle paragraph. However, with respect to whether Fortran had implied type conversion: Fortran II certainly did, across an assignment operator: both float = int expression and int = float expression were allowed. Exponentiation of a float to an integer power was also allowed. Generalized mixed-mode expressions were not allowed, however. | |
| Feb 5, 2019 at 18:20 | comment | added | Felix Palmen | Again here, how does "which was the first programming language that had data types?" ask anything about type conversions? | |
| Feb 5, 2019 at 17:06 | comment | added | Raffzahn | Except, that Fortran did no implied type conversion - at least not prior to the introduction of intrinsics inserted into assignment evaluations in FORTRAN 77. Way after ALGOL 60. (Intrinsics itself where introduced in Fortran 66). | |
