MATH_POLYNOMIAL_ROUND_BOUNDARY [line 32]

MATH_POLYNOMIAL_ROUND_BOUNDARY = 0.0001

Rounding boundary for numbers that get multiplied together

If we multiply two numbers, 0.33333 and 3, should we round this result to 1, or leave it as 0.99999? If the difference between 1 and 0.99999 is less than $_round_boundary it will be rounded to 1, otherwise it will be left as a float.

This only gets defined if it's not defined already, allowing the user to define this for themselves if they'd like better/worse precision. Setting this lower gives better precision... setting it too low makes some multiplication look funny and can make division fail.
