SFR formats the value to significant figures (digits) as specified.
SYNTAX:
SFR(Value,SignificantDigits,MaxDecPlaces,RoundType)
Value: Value to be formatted. Can be value, cell reference, or another function.
SignificantDigits: Number of Significant Figures (Digits)
MaxDecPlaces: Maximum number of Decimal Places.
RoundType: Sets rounding type. See Scientific vs Normal Rounding for more info on rounding. Valid settings are:
1 - Scientific
2 - Normal
3 - Truncate
NOTES:
This function can be placed by using the Format, Rounding menu option. Rules for significant figures:
-
Digits from 1-9 are always significant.
-
Zeros between two other significant digits are always significant
-
One or more additional zeros to the right of both the decimal place and another significant digit are significant.
-
Zeros used solely for spacing the decimal point (placeholders) are not significant.

Why was the last one 3.05? Examining our formula we see we wanted 4 significant digits, therefore the function narrows our number from 3.0447 to 3.045 first. Then the function rounds 3.045 by rule #2 to 2 decimal places - giving us 3.05.
