WebDec 1, 2024 · In a C program, unless you're using the macro to call this function, erf and erfc always take and return a double. If you use the erf() macro, the type of the argument determines which version of the function is selected. See Type-generic math for details. By default, this function's global state is scoped to the application.

WebPrior to Julia 0.6, these functions were available in Julia's Base module. Because of this, the symbols from this package are not exported on Julia 0.5 to avoid name conflicts. In this case, the symbols will need to be explicitly imported or called with the prefix SpecialFunctions. This is not necessary for Julia versions 0.6 and later. instinct raw market cat foodWebWidth: 380 px. Tip: The widget is responsive to mobile devices.
