Lahey/Fujitsu Fortran



Compile only. Default: -ndbl

Specify -dbl to extend all single-precision REAL and single-precision COMPLEX variables, arrays, constants, and functions to 64 bit double-precision. If you use -dbl, all source files (including modules) in a program should be compiled with -dbl. Specifying -dbl may or may not result in a somewhat slower executable.

Visual Studio Property

The -dbl option corresponds to the Fortran|Precision|Extend Single Precision Real property. This property can be set on the property page for the project or source file.
