Detailed Description

A thin wrapper for a fixed-precision floating point number.

This class is immutable, you may not change the contents of the object. (All operations on it create a new object.)

Constructor & Destructor Documentation

MFFloat() [1/2]

MFFloat

(

string

svalue

)

Constructor which accepts a string value.

MFFloat() [2/2]

MFFloat

(

long

value

)

Constructor which accepts a raw long value (integer offset by 10^9).

Member Function Documentation

longValueOf()

static long longValueOf ( string  s )

static

Returns a long value for the given string representation of a FP number.

This will throw an exception is the format is invalid.

valueOf() [1/2]

static MFFloat valueOf ( string  s )

static

Returns a MFFloat object for the given string representation of a FP number.

valueOf() [2/2]

static MFFloat valueOf ( double  d, int  precision  )

static

Returns a MFFloat object for the given string representation of a FP number.

toLong()

long toLong

(

)

Provide access to the raw long value.

toDouble()

double toDouble

(

)

Convert the value to a double.

(Don't use this if you care about precision.)

ipart()

long ipart

(

)

Return the integer portion of the numerical value.

fpart()

int fpart

(

)

Return the fractional portion of the numerical value, as an integer which represents the number of billion'ths, without the sign.

ToString()

override string ToString

(

)

Convert the value to a human-readable string.

Equals()

override bool Equals

(

System.Object

obj

)

operator==()

static bool operator== ( MFFloat  c1, MFFloat?  c2  )

static

operator!=()
