| Subject: | (EXPR) Integer divisions don't return floats |
When you perform calculations in EXPR on integers, only integers are
returned (outputted), but divisions for example don't always return
integers. For example:
<TMPL_VAR EXPR="1/3"> == 0
<TMPL_VAR EXPR="1.0/3.0"> == 0.333333
<TMPL_VAR EXPR="2/3"> == 0
<TMPL_VAR EXPR="2.0/3.0"> == 0.666667
This can become quite annoying when using variables:
<TMPL_VAR EXPR="sprintf('%.2f', (part/total*100))"> %
The 2 digits after the decimal point will be zero when either the
variable 'firstpart' or 'total' is an integer. The following ugly hack
will give the expected result:
<TMPL_VAR EXPR="sprintf('%.2f', (sprintf('%f', part)/sprintf('%f',
total)*100.0)"> %
I'm using perl 5.8.7 i686-linux-thread-multi and HTML::Template::Pro 0.64
