fmod() is a modulo function that returns the remainder part of the division of the first argument (the dividend) by the second argument (the divisor). The result is a real number. Both arguments are interpreted as real numbers, that is, they do not have to be integers.
Syntax:
fmod(a, b)
Return data type: numeric
Examples and results:
- fmod( 7,2 ): returns 1
- fmod( 7.5,2 ): returns 1.5
- fmod( 9,3 ): returns 0
- fmod( -4,3 ): returns -1
- fmod( 4,-3 ): returns 1
- fmod( -4,-3 ): returns -1
