DelphiBasics Round Function Rounds a floating point number to an integer System unit

function Round(const Number Extended):Int64;

Description The Round function rounds a floating point Number to an Integer value.   The rounding uses Bankers rules, where an exact half value causes a rounding to an even number:   12.4 rounds to  12 12.5 rounds to  12 // Round down to even 12.6 rounds to  13   13.4 rounds to  13 13.5 rounds to  14 // Round up to even 13.6 rounds to  14 Notes The Trunc function does the same, but returns the integer in an Integer value. Related commands Frac The fractional part of a floating point number Int The integer part of a floating point number as a float Trunc The integer part of a floating point number  Download this web site as a Windows program.

Example code : A simple example begin   ShowMessage('Round(12.75) = '+IntToStr(Round(12.75)));   ShowMessage('Trunc(12.75) = '+IntToStr(Trunc(12.75)));   ShowMessage('  Int(12.75) = '+FloatToStr(Int(12.75)));   ShowMessage(' Frac(12.75) = '+FloatToStr(Frac(12.75))); end; Show full unit code   Round(12.75) = 13   Trunc(12.75) = 12    Int(12.75) = 12    Frac(12.75) = 0.75
