Fixed the name.

isinf/isnan/finite are not C89 so I get these warnings due to
--no-ansi-c.

float.m: In function ‘float_module22’:
float.m:718:5: warning: implicit declaration of function ‘isinf’ [-Wimplicit-function-declaration]
float.m: In function ‘float_module23’:
float.m:680:5: warning: implicit declaration of function ‘isnan’ [-Wimplicit-function-declaration]
float.m: In function ‘float_module26’:
float.m:753:5: warning: implicit declaration of function ‘finite’ [-Wimplicit-function-declaration]

Not sure what the fix should be.
