CVTSI2SS
Converts a signed integer source to a scalar single-precision floating-point value. The conversion is performed according to the rounding control in the MXCSR register.
The table below covers the supported source and destinations.
| source | destination(s) |
|---|---|
| r32 / m32 | f32 |
DO NOT support LOCK
This instruction is available in both 32-bit and 64-bit modes. It requires SSE support.
The destination must be an XMM register; memory-to-memory operations are NOT supported. When the source value is too large to be represented exactly in the single-precision format, the result is rounded according to the rounding mode specified in MXCSR. If the result cannot be represented, it MAY trigger #O or #P.
