Arithmetic floating-point operations.
In safe mode, these procedures throw a type error when given non-float arguments. In unsafe mode, these procedures do not check their arguments. A non-flonum argument in unsafe mode can crash the application.
Note: fpround uses the rounding mode that your C library implements, which is usually different from R5RS.
