Function

trunc( value, numberOfDecimals )

Truncates a decimal number to the specified number of places after the decimal point.

Parameters

Keyword	Type	Description
value	Decimal	A decimal number.
numberOfDecimals	Number	The number of places after the decimal point to which the number should be truncated.

Decimal

Usage considerations

If the numberOfDecimals parameter is not specified, a default value of 0 is used and the decimal number is truncated to just its integer value.

Appian stores the Number (Decimal) data type as a double precision floating-point decimal, which is a 64-bit IEEE 754 floating point. You may experience unexpected results when using this function due to a limitation with the IEEE 754 standard. Refer to Appian Knowledge Base article #1426 for more details and suggested workarounds.
