Hello!
I want to evaluate some mathematical expressions in a script and I try to use 'expr' command.
Unfortunatally, when I have, for example,
expr 8.2 + 6
the result is 'expr: non-numeric argument'
Why ?
I work on SunOs 5.7.
Thanks in advance

aic
AIC(4) BSD/i386 Kernel Interfaces Manual AIC(4) NAME
aic -- Adaptec AIC-6260 and AIC-6360 SCSI driver SYNOPSIS
device aic In /boot/device.hints: hint.aic.0.at="isa" DESCRIPTION
The aic driver provides support for the Adaptec AIC-6260 and AIC-6360 SCSI controller chips. Many systems that use these controller chips do not have a boot ROM and therefore cannot be booted from. HARDWARE
The adapters supported by the aic driver include: o Adaptec AHA-1505 (ISA) o Adaptec AHA-1510A, AHA-1510B (ISA) o Adaptec AHA-1520A, AHA-1520B (ISA) o Adaptec AHA-1522A, AHA-1522B (ISA) o Adaptec AHA-1535 (ISA) o Creative Labs SoundBlaster SCSI host adapter (ISA) o Adaptec AHA-1460, AHA-1460B, AHA-1460C, AHA-1460D (PC Card) o Adaptec AHA-1030B, AHA-1030P (PC98) o NEC PC-9801-100 (PC98) SEE ALSO
aha(4), ahb(4), ahc(4), cd(4), ch(4), da(4), intro(4), sa(4) BUGS
The driver does not work well with multiple devices on the SCSI bus. The driver works well with devices like CDROMs and Tape drives. The driver works not so well with disk drives. The PC Card version appears to work better than the ISA version, but that may be due to differing levels of testing of the devices. BSD
