## 8.105 Math::BigFloat

Provides methods that permit use of floating-point numbers of arbitrary length. The following apply to all methods, except as noted:

- The object `$f` remains unchanged.

- All methods except `fcmp` return a number string (`nstr`) of the form `/[+-]\d+E[+-]\d+/`, with embedded whitespace ignored.

- A return value of `NaN` indicates either that an input parameter was "Not a Number" or that an illegal operation was attempted.

- A similar default scale value is computed for square roots.

- new
- fabs
- fadd
- fcmp
- fdiv
- ffround
- fmul
- fneg
