Attempting to bring writeIEEE754 performance closer to that of
DataView's setFloat32. These few small changes increase performance by
about 20%. They include:
- Removal of isNaN() checks. Arguments are controlled, so no need for
- Variable rt wasn't caching a static result. Added that as constant at
top of script.
- Inlined the absolute assignation of value.
- Assigned more values at beginning because of previous.
