Floating point does not always represent some numbers precisely
0.5 and 0.25 are simple binary fractions of 1, floating point will represent it perfectly as long as it has 2+ bits of fraction. For 32-bit floats, anything inside +/-2 million will work perfectly.

Computationally speaking, this is the most direct method: Multiply by 4, strip off decimals, divide by 4.
Code:
Math.floor(var*4) / 4
