Int

Syntax:

    integer_variable = Int( single_variable )

Command Availability:

Available on all microcontrollers.

Explanation:

The Int function truncates a floating-point (Single) value down to its integer part, discarding the fractional part (it does not round). The result is returned as an integer, so it must fit within the integer variable range.

Example:

    Dim singlevariable As Single
    Dim integer_value As Integer
    singlevariable = 7.85

    integer_value = Int( singlevariable )          ' <<< the Int instruction
    ' integer_value now holds 7

Key line: Int( singlevariable ) — drops the .85 fractional part of 7.85, leaving the integer value 7 (not rounded to 8).
