This template produces an expression for the truncated value of a given expression. If the value is in the range of integer-type numbers (in the range {{numf|trunc-2^63}} through {{numf|trunc(2^63-1024)+trunc1023}}), the resulting expression is of type integer.

The template also serves as a tool to enter an integer larger than {{numf|2^53}}, avoiding rounding to float: split the digits up into two parameters, each forming an integer not larger than that limit, and avoiding leading zeros in the second parameter. If the latter requires a larger first parameter: for every trailing 0 it can be a factor 2 larger then mentioned (see also [[Help:Calculation accuracy#Integers]]). To enter an integer smaller than -{{numf|2^53}} explicitly, do the same with a minus sign before each part.

Thus, when applying <code>#expr</code>, if the value is in the range of integer-type numbers the exact result is produced. The reason for not applying <code>#expr</code> in this template is:
* for integer-type numbers: in subsequent use in another expression the value would be rounded to float
* for floats: they would be rounded to 14 digits
