This template rounds towards zero (aka '''truncates''') a numeric expression to a limited number of decimal places.

; Usage:
: {{Tlx|{{PAGENAME}}|''expression''}}
: {{Tlx|{{PAGENAME}}|''expression''|''decimals''}}
: Both parameters can be any valid numeric expression.
: The ''decimals'' parameter defaults to 0 and is rounded to the nearest integer.
: ''decimals'' can be negative to round down to a multiple of a power of ten.
; Examples:
: {{Tlx|{{PAGENAME}}|3.14159|3}} = {{{{PAGENAME}}|3.14159|3}}
: {{Tlx|{{PAGENAME}}|-3.14159|3}} = {{{{PAGENAME}}|-3.14159|3}}
: {{Tlx|{{PAGENAME}}|314159|-3}} = {{{{PAGENAME}}|314159|-3}}
: {{Tlx|{{PAGENAME}}|-314159|-3}} = {{{{PAGENAME}}|-314159|-3}}
: {{Tlx|{{PAGENAME}}|+1/3}} = {{{{PAGENAME}}|+1/3}}
: {{Tlx|{{PAGENAME}}|2<1}} = {{{{PAGENAME}}|2<1}}
: {{Tlx|{{PAGENAME}}|-1/3}} = {{{{PAGENAME}}|-1/3}}
: {{Tlx|{{PAGENAME}}|-2/3}} = {{{{PAGENAME}}|-2/3}}
;For expressions containing '''equal signs''' use <tt>1=</tt>''expression'' - the second example fails:
: {{Tlx|{{PAGENAME}}|<nowiki>1=3<=4</nowiki>}} = {{{{PAGENAME}}|1=3<=4}}
: {{Tlx|{{PAGENAME}}|<nowiki>3<=4</nowiki>}} = {{{{PAGENAME}}|3<=4}}
