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.
