smarty中的數學運算

{* $height=4, $width=5 *}

{math equation="x + y" x=$height y=$width}

OUTPUT:

9

{* $row_height = 10, $row_width = 20, #col_div# = 2, assigned in template *}

{math equation="height * width / division"
      height=$row_height
      width=$row_width
      division=#col_div#}

OUTPUT:

100

{* you can use parenthesis *}

{math equation="(( x + y ) / z )" x=2 y=10 z=2}

OUTPUT:

6

{* you can supply a format parameter in sprintf format *}

{math equation="x + y" x=4.4444 y=5.0000 format="%.2f"}

OUTPUT:

9.44
