Takes 1 arguments

double

Rounds and converts number to the next lower NixInt value if possible, i.e. floor *number* <= *number* and *number* - floor *number* < 1.

An evaluation error is thrown, if there exists no such NixInt value floor *number*. Due to bugs in previous Nix versions an evaluation error might be thrown, if the datatype of number is a NixInt and if *number* < -9007199254740992 or *number* > 9007199254740992.

If the datatype of number is neither a NixInt (signed 64-bit integer) nor a NixFloat (IEEE-754 double-precision floating-point number), an evaluation error will be thrown.

This function is not defined in a .nix file. It is likely a builtins function or an alias of a builtins function. builtins functions are predefined functions provided by Nix.
