AlmostEqual()

static proto bool float.AlmostEqual ( float  a, float  b, float  epsilon = 0.0001  )

static

Return true when difference of two given float values is less or equal then epsilon.

float a = 1.0;
float b = 1.001;
 
if (float.AlmostEqual(a,b))
    Print("are almost equal");
 
>> 'are almost equal'

Sign()

proto external int float.Sign

(

)

Returns an integer that indicates the sign of a number.

• For floatNumber.Sign() < 0 result is -1.
• For floatNumber.Sign() == 0 result is 0.
• For floatNumber.Sign() > 0 result is 1.

ToString()

proto external string float.ToString	(	int	len = -1,
		int	lenDec = -1
	)

Float to string with fixed length, padded with zeroes.

Parameters

len	int fixed length (overall including decimal part and floating point mark)
lenDec	int fixed length of decimal part float num = 123.456; string s1 = num.ToString(10, 4); string s2 = num.ToString(); Print(s1); Print(s2); >> s1 = '00123.4560' >> s2 = '123.456'
