In older versions of FPC that support operator overloading you can add this feature yourself. The result is the same as the fmod function for the highest precision available for the platform. It is awesome in it's capability to write what you need and even design the input screens to look very clean and professional.
#PLANSWIFT 10 ROUND NUMBERS MOD#
This is equivalent to I mod J = I - int(I / J) * J. Planswift is like an open-source, do-it-yourself platform.
The precision used is the highest precision available for the platform.įor instance, the expression "a:= 12.9 mod 2.2 " would evaluate to 1.9. This is also what most other languages like C++ and Java do (see note)įrom version 3.1.1 FreePascal also supports the mod operator for floating point values when you include the math unit. In fact, the Mod operator is equivalent to the following operation :" I mod J = I - (I div J) * Jįor example "c:= -13 mod 4 " results in c = -1 and "c:= 10 mod -3 " results in c = 1. "The sign of the result of a Mod operator is the same as the sign of the left side operand of the Mod operator. Mod ( modulus) divides two numbers and returns only the remainder.įor instance, the expression "a:= 13 mod 4 " would evaluate to 1 (a=1), while "b := 12 mod 4 " would evaluate to 0 (b=0). Example: 73 rounded to the nearest ten is 70, because 73 is closer to 70 than to 80. The result is less accurate, but easier to use. 2/5 Example 0.5 will round to 0 0.75 will round to 1 1. Parameters Expression This is a value to be rounded. This method of rounding is often called 'Bankers Rounding'. │ Deutsch (de) │ English (en) │ français (fr) │ Rounding means making a number simpler but keeping its value close to what it was. If X is exactly halfway between two whole numbers (X.5), the result is always the even number.
