WebMay 20, 2013 · I agree that the divide by zero exception would be more intuitive for debugging (is debugging ever intuitive though?) this case, but I don't think that will change since in addition to intel's docs, the fortran standard (ISO/IEC 1539-1:2010 draft) defines the divide by zero fp exception as having non-zero numerators. WebMay 28, 2024 · I am trying to divide matrices in Fortran (f90). X=R/Z => X [6x1], R [6x6] and Z [6x1] are matrices. Normally in Matlab, You can write that equation and easy but in Fortran little bit different because Fortran has no any division properties so that I need to take the inverse of Z matrix (X=R*Z^-1). The problem is matrix shape because here Z ... WebIn addition to addition +, subtraction -, multiplication * and division /, Fortran has an exponential operator **.

As this is a so-called level-2 expression I'll explain only in terms up to that.

In FORTRAN, addition and subtraction are denoted by the usual plus (+) and minus (-) signs. Multiplication is denoted by an asterisk (*). This symbol must be used to denote every multiplication; thus to multiply N by 2, we must use 2 * N or N * 2 not 2N. Division is denoted by a slash (/), and exponentiation is … See more Providing all variables and constants in the expression are real, real arithmetic will be carried out as expected, with no decimal places being truncated.
