Math Question, decimal truncated, want to see up to 2 decimal places
|
Some math, should add up to 640 and in the end show a value of 6.40 or 6.4 but it does not, instead it shows a value of 6
| Code: |
| #alias testmath {eq_mystats=0.00;eq_mystats=(@eq_mystats+(100*0.5*2));eq_mystats=(@eq_mystats+(100*1*3));eq_mystats=(@eq_mystats+(100*0.4*3));eq_mystats=(@eq_mystats+(100*0.2*6));#show (@eq_mystats/100)} |
How do I need to do my math so that I am able to see the decimal up to 2 places |

OK strange the above example works but this one does not:
| Code: |
| #alias testmath2 {eq_mystats=(640*1.00);#show (@eq_mystats/100)} |

Interesting. Neither %float nor %format work like they say they are supposed to.

| Code: |
| eq_mystats=%float(640*1.00) |
Works |

You're either always going to care about the decimal of a particular number or you never will, so just use %float for those numbers that you care about.

Doing:
#show (@eq_mystats/100.0)
will also work. If the variable is set to auto-type, then CMUD only does floating-point math if you specifically put the decimal point on the numbers (like 100.0).
Otherwise you have to set the variable to be a Float type as you mentioned. |
