Math.fround() — Exact in Float32

📖 Usage Example

// Nearest 32-bit single-precision float
Math.fround(1.337)   // → 1.3370000124...
Math.fround(1.5)     // → 1.5

Use Math.fround() to convert a number to the nearest 32-bit float, useful when working with WebGL or typed arrays.

Math.fround()

Returns the nearest 32-bit single precision float representation of a number.

Challenge: Verify that Math.fround(1.5) is exactly 1.5 since 1.5 is representable in 32-bit float.
