## FloatingPointComparisonDivideRoundTripIsGreaterOrEqual Method |

Divides a dividend by a divisor such that if the quotient is later multiplied by the
divisor the result is greater than or equal to the dividend.

Syntax

public static double DivideRoundTripIsGreaterOrEqual( double dividend, double divisor )

- dividend
- Type: SystemDouble

The dividend. - divisor
- Type: SystemDouble

The divisor.

The quotient.

Remarks

If floating point numbers were infinitely precise, this method would be unnecessary.
Since they're not, this method allows you to have control over how the error falls.
For example, imagine that you have a floating point number that represents the minimum
value allowed as input to a function. You want to express that minimum value in a
different set of units such that the user can pass the minimum value to the function in
that different set of units. By using this method to do the conversion to the alternate
set of units, you guarantee that upon converting that value back to the original set
of units the value will be greater than or equal to the original minimum value. Using a
normal division might cause the value to actually be less than the minimum upon doing the
round-trip conversion, which would likely cause the function to fail.
