Question

How to use fmod() function to get the floating-point remainder (modulo) of the division x/y in PHP

Answer 1

echo "fmod(4.3 . 2.0) = " . fmod (4.3 , 2.0) . "<br />";
echo "fmod(18.5 . 4.2) = " . fmod(18.5 , 4.3) . "<br />";
echo "fmod(5.1 . 3.0) = " . fmod(5.1 , 3.0) . "<br />";
echo "fmod(-5.1 . 3.0) = " . fmod(-5.1 , 3.0) . "<br />";
echo "fmod(5.1 . -3.0) = " . fmod(5.1 , -3.0) . "<br />";
echo "fmod(-5.1 . -3.0) = " . fmod(-5.1 , -3.0) . "<br />";
echo "fmod(0.0 . 1.0) = " . fmod(0 , 1.0) . "<br />";
echo "fmod(-0.0 . 1.0) = " . fmod(-0.0 , 1.0) . "<br />";
echo "fmod(3.1 . INF) = " . fmod(3.1 , INF) . "<br />";


/*
run: 

fmod(4.3 . 2.0) = 0.3
fmod(18.5 . 4.2) = 1.3
fmod(5.1 . 3.0) = 2.1
fmod(-5.1 . 3.0) = -2.1
fmod(5.1 . -3.0) = 2.1
fmod(-5.1 . -3.0) = -2.1
fmod(0.0 . 1.0) = 0
fmod(-0.0 . 1.0) = 0
fmod(3.1 . INF) = NAN
