This can be tested, for example, by giving the command `tt(print - $(( 12345678901 )))'; if the number appears unchanged, the precision is at least 8 bytes. Floating -point arithmetic is always double precision. +point arithmetic always uses the `double' type with whatever corresponding +precision is provided by the compiler and the library. The tt(let) builtin command takes arithmetic expressions as arguments; each is evaluated separately. Since many of the arithmetic operators, as well -- cgit 1.4.1
