Convert binary string representation of a number to floating point (String class)
BinaryToFloat is an intrinsic function converts a binary string representation of a floating point number to that number.
Syntax
%number = string:BinaryToFloat
Syntax terms
| %number | A numeric variable to receive the float value of the method object string. |
|---|---|
| string | A binary string value that can have a length of 4, 8, or 16 bytes. |
Usage notes
- BinaryToFloat is available as of Sirius Mods version 7.5.
Examples
The following program demonstrates the BinaryToFloat method, converting a series of different-length representations of the same float value.
begin image silly a is float len 4 b is float len 8 c is float len 16 end image prepare image silly %i is float %s is string len 30 for %i from -3.3 to 3.3 by 1.1 printText {%i:right(15)}: %silly:a = %i; %silly:b = %i; %silly:c = %i; %s = $lstr_get_image('SILLY') printText {~} = {%s:stringToHex} printText {~} = {%s:subString(1, 4):binaryToFloat} printText {~} = {%s:substring(5, 8):binaryToFloat} printText {~} = {%s:substring(13, 16):binaryToFloat} end for end
The result is:
-3.3: %s:stringToHex = C134CCCDC134CCCCCCCCCCCCC134CCCCCCCCCCCC0000000000000000 %s:substring(1, 4):binaryToFloat = -3.30000019073486 %s:substring(5, 8):binaryToFloat = -3.3 %s:substring(13, 16):binaryToFloat = -3.3 -2.2: %s:stringToHex = C1233333C123333333333333C1233333333333330000000000000000 %s:substring(1, 4):binaryToFloat = -2.19999980926514 %s:substring(5, 8):binaryToFloat = -2.2 %s:substring(13, 16):binaryToFloat = -2.2 -1.1: %s:stringToHex = C111999AC111999999999999C1119999999999990000000000000000 %s:substring(1, 4):binaryToFloat = -1.10000038146973 %s:substring(5, 8):binaryToFloat = -1.1 %s:substring(13, 16):binaryToFloat = -1.1 0: %s:stringToHex = 00000000000000000000000000000000000000000000000000000000 %s:substring(1, 4):binaryToFloat = 0 %s:substring(5, 8):binaryToFloat = 0 %s:substring(13, 16):binaryToFloat = 0 1.1: %s:stringToHex = 4111999A411199999999999941119999999999990000000000000000 %s:substring(1, 4):binaryToFloat = 1.10000038146973 %s:substring(5, 8):binaryToFloat = 1.1 %s:substring(13, 16):binaryToFloat = 1.1 2.2: %s:stringToHex = 41233333412333333333333341233333333333330000000000000000 %s:substring(1, 4):binaryToFloat = 2.19999980926514 %s:substring(5, 8):binaryToFloat = 2.2 %s:substring(13, 16):binaryToFloat = 2.2 3.3: %s:stringToHex = 4134CCCD4134CCCCCCCCCCCC4134CCCCCCCCCCCC0000000000000000 %s:substring(1, 4):binaryToFloat = 3.30000019073486 %s:substring(5, 8):binaryToFloat = 3.3 %s:substring(13, 16):binaryToFloat = 3.3
