=head2 $confidence = B<Math::NumberCruncher::SignSignificance>($trials,$hits,$probability);

Returns the probability of how likely it is that your data is due to chance.  The lower the confidence, the less likely your data is due to chance.

=head2 $e = B<Math::NumberCruncher::EMC2>( "m36", "km" [, $decimal_places] );

Implementation of Einstein's E=MC**2.  Given either energy or mass, the function returns the other. When passing mass, the value must be preceeded by a "m," which may be either upper or lower case.  When passing energy, the value must be preceeded by...

=head2 $force = B<Math::NumberCruncher::FMA>( "m97", "a53" [, $decimal_places] );

Implementation of the stadard force = mass * acceleration formula.  Given two of the three variables (i.e., mass and force, mass and acceleration, or acceleration and force), the function returns the third.  When passing the values, mass must be prec...

=head2 $predicted = B<Math::NumberCruncher::Predict>( $slope, $y_intercept, $proposed_x [, $decimal_places] );

Useful for predicting values based on data trends, as calculated by BestFit(). Given the slope and y-intercept, and a proposed value of x, returns corresponding y.

=head2 $area = B<Math::NumberCruncher::TriangleHeron>( $a, $b, $c [, $decimal_places] );

Calculates the area of a triangle, using Heron's formula.  TriangleHeron() can be passed either the lengths of the three sides of the triangle, or the (x,y) coordinates of the three verticies.

=head2 $perimeter = B<Math::NumberCruncher::PolygonPerimeter>( $x0,$y0, $x1,$y1, $x2,$y2, ... [, p$decimal_places]);

Calculates the length of the perimeter of a given polygon. The final argument specifies the number of decimal places you want. To specify a number other than the default (see above), the number must be preceeded by the letter "p". For example: Math::...

=head2 $direction = B<Math::NumberCruncher::Clockwise>( $x0,$y0, $x1,$y1, $x2,$y2 );

Given three pairs of points, returns a positive number if you must turn clockwise when moving from p1 to p2 to p3, returns a negative number if you must turn counter-clockwise when moving from p1 to p2 to p3, and a zero if the three points lie on the...

=head2 $collision = B<Math::NumberCruncher::InPolygon>( $x, $y, @xy );

=head2 $volume = B<Math::NumberCruncher::SphereVolume>( $radius [, $decimal_places] );

Calculates the volume of a sphere, given the radius.

=head2 $surface_area = B<Math::NumberCruncher::SphereSurface>( $radius [, $decimal_places] );

Calculates the surface area of a sphere, given the radius.

=head2 $years = B<Math::NumberCruncher::RuleOf72>( $interest_rate [, $decimal_places] );

A very simple financial formula. It calculates how many years, at a given interest rate, it will take to double your money, provided that the money and all interest is left in the account.

=head2 $volume = B<Math::NumberCruncher::CylinderVolume>( $radius, $height [, $decimal_places] );

Calculates the volume of a cylinder given the radius and the height.

=head2 $volume = B<Math::NumberCruncher::ConeVolume>( $lowerBaseArea, $height [, $decimal_places] );

Calculates the volume of a cone given the lower base area and the height.

=head2 $radians = B<Math::NumberCruncher::deg2rad>( $degrees [, $decimal_places] );
