problems with decimal numbers
|
im trying to monitor my stam use per round
here is an example of two rounds
ST[31.95%]
ST[30.52%]
here is my trigger
ST~[(%d)~.(%d)~%~]
the problem i am having is the decimal number, im not sure how to put a decimal value number into a variable then find the difference from the previous value. If anyone has any ideas on this id be thankful. |

Thanks, that seems so simple im sorry to trouble you.
I am having a small problem though.
Why does my stamdiff variable go out so many decimal places
#VAR stam %5.%6
#MATH stamdiff (@stamp - @stam)
#VAR stam
#VAR stamp
#VAR stamdiff
#VAR stamp %5.%6
Variable: stam 71.14
Variable: stamp 71.95
Variable: stamdiff 0.80999755859375 |

Use
| Code: |
| %left(@stamdiff, 4) |
to format the outcome to in this case "0.80". If you want it to round off properly will you have to make a function that checks the fifth letter and act on it.
Edit: Oh, and to answer your question of "Why?". The computer sees it as a "double" (data type) and calculates the answer, doubles ain't very precise though and thus the odd answer. |

There's a built-in function that normalizes a decimal number. You might wish to look into using that instead of %left().
