Detailed Description

A Real value implements floating point operations on the CPU. It does not adhere any any IEEE standard, but has the extremely important attribute of providing identical semantics on every CPU which executes it. This is otherwise impossible to guarantee in the CLR, especially when 3rd party code is running and/or C++ DLL access is unavailable to set x87 FPU rounding modes.

Member Function Documentation

static Real Forge.Utilities.Real.CreateDecimal	(	long	beforeDecimal,
		int	afterDecimal,
		int	afterDigits
	)

static

Creates a real value with that is 0.number. For example, CreateDecimal(123) will create a real value that is equal to "0.123".

CreateDecimal(1, 0005, 4) will create 1.0005 CreateDecimal(1, 5, 4) will create 1.0005

Returns

static Real Forge.Utilities.Real.FromParts	(	int	PreDecimal,
		int	PostDecimal
	)

static

Create a fixed-int number from parts. For example, to create 1.5 pass in 1 and 500.

Parameters

PreDecimal	The number above the decimal. For 1.5, this would be 1.
PostDecimal	The number below the decimal, to three digits. For 1.5, this would be 500. For 1.005, this would be 5.

Returns: A fixed-int representation of the number parts
