Floor()

Floor()

Rounds down a number to the next integer

Syntax

      Floor( <nNumber> ) -> <nDownRoundedNumber>

Arguments

<nNumber> number to round down

Returns

<nDownRoundedNumber> the rounded number

Description

The function Floor() determines the biggest integer that is smaller than <nNumber>.

Examples

      ? Floor( 1.1 )  // --> 1.0
      ? Floor( -1.1 ) // --> -2.0

Tests

      Floor( 1.1 )  == 1.0
      Floor( -1.1 ) == -2.0

Compliance

Floor() is compatible with CT3’s Floor().

 CEILING()
 Rounds up to the next integer
------------------------------------------------------------------------------
 Syntax

     CEILING(<nValue>) --> nLargerInteger

 Argument

     <nValue>  Designates the number for which the next-largest integer
     is determined.

 Returns

     CEILING() returns the next-largest integer to the one that is passed as
     a parameter.

 Description

     CEILING() returns the next-largest integer to the one passed as a
     parameter.  This applies to positive and negative numbers.

 Example

     Show the next-largest integer (including positive and negative numbers):

     ? CEILING(1.9)            // Result:   2
     ? CEILING(1.1)            // Result:   2
     ? CEILING(0.9)            // Result:   1
     ? CEILING(-0.1)           // Result:   0
     ? CEILING(-0.9)           // Result:   0
     ? CEILING(-1.1)           // Result:-1
